A look at the long-term effectiveness of an integrated tinnitus management approach (WZT) and the pattern of amplification and sound therapy use among primary tinnitus patients once successful remediation of symptoms is achieved. Habituation is classically defined as the process of adapting to a stimulus through repeated exposure. The attentional processes involve perceptual filters that determine which sensory perceptions are brought to our conscious attention.
The vast majority of tinnitus patients present at least some degree of hearing loss, fueling the theory that the central auditory nervous system responds to the hearing deficit by increasing its gain, further adding to the perception of tinnitus.
The use of music has been shown to reduce stress hormones.10 Physiological and behavioral reactions to tinnitus can be mitigated through the use of music.
Hearing aids with either noise generators or some kind of music have become popular in tinnitus management.
Consequently, there is a growing consensus that a multifaceted individualized approach to tinnitus management is more likely to result in the best outcomes.
In addition, WZT incorporates the use of fractal (commercially termed Zen) tones and broadband amplification characterized by an extremely low compression kneepoint, relaxation exercises, and sleep management. The effectiveness of WZT in several studies has been reported,1,18-19 but none of these investigations have indicated the effectiveness or usage characteristics beyond a 6-month period. All participants were given a comprehensive audiologic and tinnitus evaluation including the Tinnitus Handicap Inventory (THI),20 Tinnitus Functional Index (TFI),21 and Widex Tinnitus Intake questionnaire.17 Participants were required to have cognitive, comprehension, and manual dexterity abilities sufficient for treatment, and all subjects paid for the tinnitus treatment for up to 12 months post hearing aid fitting. Additionally, all subjects were fit with Widex Dream or Clear hearing aids containing fractal (Zen) tones.
Even though the initial fitting met most subjects’ needs, some required individual modifications in their Zen + programming. Subjects were instructed to use the devices during their waking hours when hearing and communication were essential.
Figure 3 depicts the relationship between TFI baseline and 12-month post WZT for individual subjects. Figure 5 shows the mean use (in time percentage) of the Zen + programs as well as the amplification alone (the “Master” program) program.
Datalogging also revealed that the Zen A (Aqua + microphone on) and Zen B (Aqua and noise plus microphone on) programs were the most frequently used programs. The use of Zen C (noise only plus microphone on) was very limited, varying from 9-12% during the 12 months. The fact that all 19 of the subjects achieved clinically significant improvements when comparing TFI scores from baseline to each of the follow-up visit scores, including those obtained at the 12-month visit, would seem to provide an unequivocal answer to that question. Unfortunately, it is impossible to determine whether the overall use of amplification increased, because even during the 48% of time in which amplification-alone wasn’t being used at the 12-month visit, 17 out of 19 subjects were still utilizing Zen + programs that contained amplification. 2) Even though subjects had achieved an acceptable resolution of their tinnitus, they still recognized, and in some cases achieved, an even greater appreciation for the benefits received from amplification—either by assisting their hearing or by continuing to minimize their tinnitus distress. Results from myriad investigations leave little doubt that WZT is an effective approach to tinnitus management. The inverse relationship between the use of Zen programs versus amplification-alone over time suggests that patients (even those whose primary complaint was tinnitus, rather than hearing loss) perceive a continued benefit for using amplification for improving their hearing, and possibly for tinnitus relief, even post habituation or successful resolution.

I remain very actively involved in the education of AuD students even though Ia€™m no longer fully employed as a faculty member at a single university. Typically when teaching a course I combine one or two intensive 3 to 5 day periods of on-campus classroom lectures and supervised laboratory sessions with regular on-line chats and lectures throughout a semester. It is sometimes hard to have a hearing issue like when you have a cold and you really can’t hear so much. Tinnitus is a very difficult condition wherein people hear strange sounds from within their ear. People who are affected by this hearing disorder may experience hearing distinct whispers, sound of a snake that is hissing, or the sound of the wind or a wave, or a sound of an insect buzzing and the condition is described as spasmodic and irregular.
It is very funny to note that the same Tinnitus symptoms are actually symptoms in themselves.
The eyes are acoustically continuous with the brain and inner ear tissues as regards matched impedances, based on tissue densities; thus, vibration of one site will be reflected in all sites. The old axiom that the eye is a window to the brain has not been found to be accurate as regards eye (intraocular) pressure reflecting brain (intracranial) pressure. It is the purpose of this study to present data from an ICP-IOP balloon model that suggest the eye may indeed reflect the acoustical properties of elevated ICP without the need for pressure correlations. After the skull model experiments, a second series on human subjects was studied under conditions of normal ambient brain pressure and elevated pressure using Valsalva maneuvers. The reverse brain-eye transmission, or the eye audiogram, was determined by delivering audio frequencies to the eye and obtaining standard audiometric thresholds. When the skull was excited with low-frequency tones, the eye responded with sympathetic vibration. Behavioral results from brain pressurization were obtained by recording the eye spectral response using broadband energy applied to the skin over the supraorbital process rather than tones, in an effort to reduce testing time and record the response over a broad range of frequencies. A clinical controversy exists regarding whether the pressure in the brain (ICP) and the pressure in the eye (IOP) correlate such that eye pressure alone could be used as a substitute for brain pressure. In 1930, Ranke25 proposed that the cerebrospinal fluid connections, or any vascular connection to the cochlea, could act as an acoustic coupler.

Single Photon Emission Computed Tomography (SPECT) of brain with technetium- 99m hexamethyl propyleneamine oxine (Tc-HMPAO) is an imaging technique which has been introduced for the identification of abnormalities of regional cerebral blood flow (rCBF) in patients with a central type of subjective idiopathic tinnitus, which was characterized as severe and disabling. Neurotologic and neurologic implications are suggested which include cerebrovascular disease, neurodegenerative disorder and dementia, and neuropsychiatric mood disorder. Tinnitus is a perceptual disorder of auditory function clinically identified to have both sensory and affect components.
SPECT imaging technique of the brain is an objective analytical detection method which provides information on regional cerebral perfusion of the brain. Previously reported analytic localization techniques for tinnitus have included electrophysiologic testing for cochleovestibular function including auditory brain stem response for the recording of auditory evoked potentials.12 SPECT provides a measurable regional metabolic correlation. Organicity of brain in tinnitus patients was first reported in a preliminary study of 10 patients, who, upon completion of an MATPP, were identified to have a predominantly central type tinnitus. Two representative cases are presented to illustrate the organicity observed in patients with a central type of tinnitus and to speculate on the implications of SPECT in neurotologic and neurologic disease, as exemplified by cerebrovascular, diseases, neurodegenerative and neuropsychiatric mood disorders. The single-photon cerebral perfusion tracer (Tc-99m HMPAO) was used in all patients in this SPECT study. Triad, that is, a state-of-the-art, tripleheaded, Anger-type gamma camera with a dedicated computer for acquisition and processing-was used to acquire a 64-frame, 3600 study. Raw data used for quantification of brain SPECT regions of interest in the three orthogonal planes of examination (i.e. Normal brain SPECT studies in the preliminary study13 demonstrated bilateral symmetrical activity in anatomic regions of interest of cortical and central gray matter (Fig.
The finding of a relatively normal deposition in the subcortical areas, motor strip cortex, and cerebellum was judged significant. Neuropsychologic evaluation questioned cognitive impairment; a borderline function range was impaired for fundamental tasks of visual perception, visual span and attention, visual reasoning, visual problem solving, and visual memory. The original tinnitus onset was in 1944 after exposure to artillery in the United States' Marine Corps, and described as right ear ring. A combined program of tinnitus control was followed, based on differentiation between its sensory and affect component. The findings reported in SPECT of brain performed on two patients with tinnitus of the severe disabling type reflect ongoing clinical experience with this technique. Auditory function can be considered to involve multiple neural networks reflecting various attributes of hearing.13 Asymmetries identified by this imaging technique may represent interruptions of normal auditory function as reflected in variations in right cerebral blood flow (CBF) that affect multiple neural networks.
Central attributes of hearing may be represented by multiple areas of the cortex now identified in part as CBF asymmetries in SIT patients with predominantly central tinnitus.
Both are speculated to be reflected in the multiple areas of cortical asymmetries as demonstrated in this studr: and reported in the initial SPECT report. Identification of attributes of tinnitus in different ROIs of brain and their attentional modulation in patients with tinnitus of the central type could provide a basis for increased accuracy of tinnitus diagnosis and its clinical application for treatment.
Identification of the affect component of severely disabling tinnitus using SPECT demonstrates impairment in rCBF in specific regions of interest known to be related to mood and memory. The medial temporal lobe system was identified to have a memory function.17,18 Reciprocal connections are presumed to exist between the hippocampus and adjacent anatomically-related cortex, including endorhinal, perirhinal, and parahippocampal cortices.
As new information adds to our understanding of the anatomy and function of the limbic system, the medial temporal lobe system studies of memory, perception, and mood can be applied to the affect component of tinnitus.
It is also hypothesized that the technique of SPECT imaging of those areas of the cortex SPECT Imaging of Brain 25 and subcortex previously identified may provide clinical manifestations of mood alteration and its relationship to a paradoxical auditory memory as reflected in asymmetries of rCBF. The affect component of the symptom of tinnitus reflects the emotional response of the patient to the presence of tinnitus.20 Emotional responses are reflected in the neurobiologic processes occurring in the brain. The multiplicity of asymmetries in various ROIs examined in brain with SPECT imaging when correlated with present knowledge of neurotransmitter function underlying a dysynchrony in neural firing within and between neural networks suggest types and subtypes of a central tinnitus. Neurologic implications for tinnitus patients are suggested by the findings of perfusion asymmetries with SPECT imaging of the brain. SPECT can differentiate between Alzheimer's disease and some other types of dementia including multi-infarct dementia, hydrocephalus, progressive supranuclear palsy, and various frontal lobe dementias. Neuropsychiatric disorders including the schizophrenias, and the affective disorders, including depression, can be demonstrated with SPECT imaging of the brain.
It has been hypothesized that there is a specific link between the thought disorder present in schizophrenia and pathologic sites in the left temporal lobe.23 The degree of thought disorder is suggested to be related to the size of the reduction in volume of the left posterior superior temporal gyrus.
SPECT studies of affective disorders including major depressive disorders show an overall decrease in regional rCBF especially in the frontallobes.26 This pattern is reported to be different from that seen in dementias. Significant involvement of hypoperfusion particularly in the frontal lobe areas has been demonstrated in our preliminary study and present case reports.
Case 1 demonstrated perfusion asymmetries in the posterior parietal, temporal, and anterior frontal lobes, with a relatively normal deposition in the subcortical areas, motor strip cortex, and cerebellum. Case 2 is considered to reflect patterns seen in cerebrovascular disease and the mood disorder of depression.
The heterogeneity of the clinical manifestations of tinnitus are considered to be reflected in the SPECT of brain imaging results obtained in our series to date and demonstrated in the two reported cases. Brain SPECT results in a particular central type SIT patient may reflect a complexity of dysfunction in neuronal networks resulting from an altered state of excitation which results in a dysynchrony in neuronal signaling, with the place of origin in the primary auditory cortex. Tinnitus, defined as a basic dysynchrony in neuronal firing within the cochleovestibular system, may specifically result in a paradoxical auditory memory center in the hippocampal amygdala complex, and other portions of the limbic system may result in varying degrees of abnormality in affect ranging from mild anxiety to severe depression.
In short, varying degrees of glutamate neurotoxicity involving neuronal networks leading from the primary auditory cortex to areas of brain function for auditory memory and affect may underlie the heterogeneity of the symptom of SIT.
No conclusion has yet been arrived at with respect to association between SIT and a cerebrovascular, neurodegenerative, and some neuropsychiatric disorders. SPECT imaging of brain in a patient with SIT is considered a significant advance for the neuroscience of tinnitus diagnosis.
Appreciation is extended to the Lionel Hampton Ear Research Foundation for its support of this effort. When tinnitus habituation occurs, either the perception of the tinnitus, or the reaction to the tinnitus, is greatly, if not fully, diminished.2 In this article, habituation will be regarded as substantial and meaningful lessening of the negative reaction to the tinnitus as defined by clinically significant reductions in subjective distress scores. The reaction to it varies from a minor annoyance to one that can significantly and negatively impact one’s quality of life. In clinically significant tinnitus, these filters determine that attention should be applied to the specific patterns of neural activity associated with the tinnitus.3,4 The engagement of the autonomic system and amygdala leads to further increases in the sensitivity of the auditory system and reinforcement of the attentional filters, creating further increase in tinnitus loudness and awareness, which in turn increases the level of stress.
A limitation of the use of popular music, however, is the chance that these stimuli can attract excessive attention to both the music and the tinnitus. Most tinnitus strategies employed over the past two decades consist of a combination of directive (instructional) counseling and acoustic stimulation (either noise, amplification, or a combination of the two).
There is also an option to include broadband noise in addition to, or in lieu of, the Zen tones.
A total of 20 subjects were initially enrolled in this cohort study conducted at the ENT Associates of South Florida in Boca Raton, Fla. The hearing loss varied from mild to moderately severe, and the average hearing thresholds of the subjects are shown in Figure 1. Clinicians participating in this investigation had considerable experience in tinnitus patient management and were familiar with the fitting of Widex hearing aids and Zen programming. The specific models chosen ranged from models 110 to 440, and were selected based on the joint decision of the patient and clinician taking in audiologic as well as economic considerations. Zen + B (noise) or Zen noise (C) were only recommended if the clients experienced periods where the tinnitus was very bothersome. Although turning off the microphone in the Zen+ programs was an option, only two subjects chose to do so. They were further taught that the Zen fractal tones should be audible, but relatively soft and that the tones should not interfere with conversational speech. The TFI and THI were administered at baseline, as well as at 2, 4, 6, 9, and 12 months post-treatment. The TFI was chosen because of its extremely strong psychometric evidence and multiple domain clinical relevance. Individual subject Tinnitus Functional Index (TFI) baseline and 12 month post Widex Zen Therapy scores for the 19 subjects.
Note that, at the 2-month visit, the three Zen + programs were used 73% of the time, but amplification-alone was only used an average of 27% of the time. Therefore, one can confidently say that, as habituation (or resolution of the tinnitus distress) increased, the need for additional sound therapy beyond amplification decreased—though subjects continued to use amplification.
It is of particular importance to note that clinically significant changes were found at the 2-month visit for all of the subjects on the TFI.


One way to approach this issue is to compare the pattern of fractal tone, noise, and amplification-only usage at the 6-month follow-up, since 15 of 19 subjects (79%) achieved clinical resolution of their tinnitus distress (<20 on the TFI) by that visit, to the 12-month follow-up visit. The exceptions were the 2 subjects who chose to turn off the microphone in Program C at the onset of the project. This is particularly relevant considering the fact that 17 of the 19 subjects originally presented with primary complaints of tinnitus, rather than hearing difficulty. As seen in earlier studies, when given the choice between listening to sound therapy containing fractal tones versus programs containing noise, the overwhelming majority (as reflected by comparing usage of Zen A vs Zen C) choose fractal tones. However, the excellent results obtained in this study are certainly, in part, related to the expertise of the clinicians. Further studies are needed to determine the relative contribution of each of the WZT components (including the undisputed importance of counseling), but until these data are available, it seems prudent to utilize the multiple counseling and sound therapy tools offered in an integrated approach like WZT.

It is spasmodic in the sense that the condition can be recurring or attacks in irregular patterns.
Only one report has described an excellent correlation between the two pressures, suggesting a possible method of noninvasive intracranial pressure (ICP) measurement based on using intraocular pressure (IOP) alone1. Supporting this model are reports that vibration applied to the eye is perceived as sound and the audiometric thresholds are similar to standard bone conduction and air conduction audiograms12-15. This model was used in previous studies with success, and details are presented there16,17. The Valsalva maneuvers were performed in five young normal individuals (institutional review board-approved) using the aforementioned recording system and experimental protocol.
The bone vibrator is placed on the eye and the accelerometer is affixed to the back of the vibrator to measure the output when mass loaded with the eye. When the brain was pressurized and the skull driven again at 500 Hz, the peak energy was also at 500 Hz but lower than the unpressurized condition by approximately 7 dBV (decibels re: 1 volt). Vibratory response of the eye balloon as a function of frequency using a forced vibration of 500 Hz delivered by a vibrator on the skull.
Vibratory response of the eye balloon with and without (baseline) forced vibration of the skull at 250 Hz. Pressurizing the brain resulted in a damped eye response- that is, reduced in amplitude at the driving frequency and reduced spectral spread. Pressurization of the brain and eye in vivo was accomplished by using a Valsalva maneuver, which increased the ICP. In one subject, vibration response of the eye induced by broadband noise delivered to the head. The concept of an eye audiogram is based on transmitting frequencies through the ocular fluid into the cerebrospinal fluid and determining subject threshold. Such a noninvasive measure of ICP would be a valuable metric in diagnosis and treatment22,23. Pressurizing the brain in a balloon model resulted in detectable acoustic changes in the eye for a broad frequency range extending to the eye's ultrasonic resonance.

SPECT results of brain demonstrate for the first time the in vivo significance of the organicity of brain for a central type of tinnitus. Clinical types of tinnitus have been identified with a Medical Audiologic Tinnitus Patient Protocol (MATPP).1 The MATPP is a unified diagnosis and treatment strategy for tinnitus. Cerebral blood flow has been correlated with function.2-8 In the determination of local brain function, the variables to be considered are cerebral blood flow (CBF) and cerebral metabolic rate (CMR).
Quantitative SPECT can potentially provide measures of structure and function, which can assist in both the diagnosis and monitoring of therapy. Cross-sectional images of radiotracer distributions were analyzed and provided a direct measure of regional organ function of the brain.
The finding of relative normal deposition in the subcortical areas, motor strip cortex, and cerebellum was of interest.
Electrical high frequency audiometry revealed positive responses of 1000 to 3000 Hz, absent at 3000 to 20000 Hz to the limits of the audiometer 60 dB sound pressure level (SPL).
Residual inhibition was measured binaurally at 10 dB re threshold of the matching 9000 Hz tone and then a 9000 Hz narrow band noise. Computerized tomograph scan of head and brain performed in 1986 was reported to be negative. The neuropsychologic profile was most consistent with significant right hemisphere abnormalities.
The parameters of tinnitus identification were described to have a quality of a high ring; ear in location, bilaterally left greater than right, constant duration, and fluctuant intensity. For the sensory component, tinnitus control initially included treatment of a presumpted secondary endolymphatic hydrops left for 4 to 6 weeks, with a trial course of systemic vestibular suppressant anti-histamine medication and diet-in the elimination or control of salt intake.
Our position is that central attributes of hearing may have as one of its symptoms of dysfunction not only interference in sound perception and speech discrimination, but also tinnitus. It would also provide a means for correlating a specific pathology with a specific physiologic attribute of tinnitus and thus lead to the development of a neuropharmacologic approach for tinnitus of a central type(s).
Clinical manifestations of alterations in the sensorium of tinnitus patients include stress, anxiety, and depression. PET and SPECT both measure regional blood flow which reflects biologic markers of local neuronal activity.
The two cases discussed in this paper support such implications and suggest the need for further investigation.
The typical finding in Alzheimer's disease is a bilateral parietotemporal hypoperfusion and hypometablism, with sparing of the sensory motor and occipital regions.
In schizophrenia, the most consistent finding has been a decrease in frontal lobe size, that is, hypofrontality, and increased rCBF in the basal ganglia, specifically the caudate, often associated with positive symptoms such as delusions and hallucinations. Postmortem CT and MRI studies have indicated that patients with schizophrenia have anatomic abnormalities in the left temporal lobe, and also that positive symptoms are related to an enlargement of the left sylvian fissure.
Such findings have been reported typical of a pattern seen with dementia of the Alzheimer's type.
TInnitus in this patient may be a soft sign of gradually progressive cerebrovascular disease.
The distribution of cortical asymmetries in the frontal, partial, temporallobes and in particular the limbic system suggest the possibility of a neurologic basis for tinnitus particularly of the central type. Such glutamate receptors mediate excitatory neurotransmission in the brain and are important in memory, speech and sound acquisition, learning, certain neurodegenerative disorders, neuronal plasticity, and neurotoxicity. Interference in glutamate neurotransmission is considered to interfere in neuron plasticity which is regulated for memory by processes of long-term potentiation (LTP) in the hippocampus and long-term depression (LTD) in the cerebellum.24 Both of these fundamental processes are considered to underlie information storage in the brain.
In any single patient, this neurotoxicity may be a forerunner of progressive degenerative diseases (including Alzheimer's disease), neuropsychiatric mood disorders, schizophrenias, cerebrovascular disease, and other central neurologic pathologies. Such a conclusion awaits neuropathologic confirmation with attention to the demonstration of a neuropathologic correlate.
This is the first time that objective asymmetry in cortical perfusion in multiple areas of brain, consistently in the left temporal lobe, has been demonstrated in consecutive tinnitus patients clinically identified to be of the predominant central type.

The condition typically involves multiple neuro-plastic changes to sites producing auditory, attentional, and emotional processes of the brain. The mechanisms of emotional disturbance associated with tinnitus define the “reaction” to hearing the tinnitus sound, as opposed to the “perception” of the sound. Auditory fractal tones utilize harmonic but unpredictable musical relationships, and are generated by a recursive process where the algorithm is applied multiple times to process its previous output.
Widex Zen Therapy extends these approaches by additionally incorporating cognitive behavioral interventions in the form of adjustment-based counseling designed to identify the unwanted thoughts and behaviors hindering natural habituation, challenge their validity, and replace them with alternative and logical thoughts and behaviors. The approach is individualized, in that the necessary components of WZT are determined after a comprehensive evaluation of the tinnitus and the patient’s reaction. All but one (19 subjects, 11 females and 8 males with a mean age of 65, ranging from 49 to 86) completed the study.
The Widex Intake Questionnaire, TFI, THI, and the clinician’s observation of the subjects were used to determine which WZT components were employed. The hearing aids had wide dynamic range compression (WDRC), compression thresholds as low as 0 dB HL, adaptive multichannel directional microphone, noise reduction, active feedback cancellation, data logging, and inter-ear capabilities.
Thus, the volume was to be set so that the annoyance level of the tinnitus would just begin to decrease. Hearing aid datalog records were accessed at these time intervals to ascertain hearing aid use both during the therapeutic effort to induce habituation and after.
Any symbol falling below this diagonal line suggests some degree of reduction in tinnitus distress. The mean use of hearing aids, including amplification and Zen programs, was 8 hours during the 12-month course of this investigation.
By the end of the study (ie, 10 months later), however, the combined use of the Zen programs had decreased to 47%, while the amplification-alone usage increased to 53%. While the effectiveness of an integrated approach like WZT has been repeatedly shown in studies cited earlier, none of those studies looked at the longer-term effects lasting out to 1 year post therapy onset. Moreover, 17 of 19 subjects (91%) had TFI scores suggesting their tinnitus was no longer clinically significant by the conclusion of the 12-month study. The data showed that the combined use of the three Zen + programs decreased from 56% to 48% (compared to 73% at the 2-month visit), while the use of the amplification-alone (Master) program progressively increased from 44% to 52% (compared to 27% at the 2-month visit).
This has been shown in other studies as well,11,12,14 and is likely due to the inherent relaxing qualities of the Zen tones.
It is not realistic to expect the 100% success found in this project to be found in the real world. The narrative is enlivened with a handful of photographs of AuD students from some of the universities. You are more likely to call in sick if something is wrong with your usual functions let alone have a hard time hearing your boss.
Most of these people experience hearing difficulties and cannot hear external sounds clearly. This is why most of the people who go to the ENT doctor will be referred further in the hospitals. Further, the model supports the observation that vibration delivered to the eye, if of sufficient intensity, can be perceived as sound, resulting in an eye audiogram similar to that obtained conventionally by bone conduction on the mastoid or forehead. However, that study result stands in stark contrast to others2-7 that reported no correlation between ICP and IOP7. Briefly, a latex balloon was threaded through the orbit to simulate an eye, with the majority of the balloon body in the cranium (calvarium removed) simulating the brain; the balloon was then filled with water. Sounds were generated by an audiometer and delivered to either the skull or the eye (in the model) or, for the hearing tests, to the eye using a standard clinical bone conduction vibrator. Under normal conditions, the ICP varies between 1 and 10 mm Hg and, after Valsalva maneuvers, pressure can increase by an additional 5 to 10 mm Hg18. The bone conduction transducer was firmly placed on the closed eyelids, carefully avoiding the bony rim of the orbit; the audible thresholds19 for audiometric frequencies from 250 to 8000 Hz were obtained for each of the five subjects.
With pressurization, the response at the skull driving frequency (250 Hz) is damped by 12 dB (re: 1 volt). The Valsalva (pressurized brain) condition resulted in lowered vibratory response of the eye by 4-6 dB depending on frequency region. With pressurization (Valsalva maneuver), the vibratory response is damped over a wide frequency range by 4-6 dB (re: 1 volt). The transducer was placed in the closed eyelid of the patient, and the intensity of the vibration varied in 5-dB steps to obtain threshold19.
Other than the ambient low-frequency noise masking in the Sinha data, the plots are in good agreement, with maximal sensitivity at 1,000 Hz. In a recent post hoc study on patients undergoing brain and eye pressure measurements, no correlation between the two was observed7. It has been demonstrated that direct audiofrequency vibration of the brain will couple to the ear and elicit evoked responses from the auditory nerve12-14. Importantly, the eye's low-frequency response is stable and much less variable than that of the skin over the skull, making feasible the possibility of clinical use of this measurement tool.

Two typical cases are presented which demonstrate significant regional abnormalities in cerebral perfusion bilateral of temporal, frontal, parietal and hippocampal amygdala regions when compared with normative Tc-HMPAO SPECT of brain data. These patients were seen for initial consultation in the Tinnitus Clinic of the Health Sciences Center at Brooklyn-State University of New York and referred for this examination.
SPECT data may reflect the physiologic test mapping of the metabolic rate of cerebral function for a particular region of interest.
An HMPAO dose of 25 mCi was administered intravenously in patient 1; and 23 mCi in patient 2, while the patient was at the basal-physiologic state, that is, with eyes and ears open. Perfusion images of the brain were obtained with a spatial resolution of 6.8 mm in the plane of the slice. Our normative qualitative data were obtained in five patients with hearing within normal ranges for speech frequencies. Tonal testing revealed negative residual inhibition on the right and a rebound effect on the left. The tinnitus intensity index rating was 6 on a 0 to 7 scale (0 meaning no tinnitus and 7 greatest severity).
The intensity was described as severe and has become left greater than right for at least 3 to 5 years before the initial consultation. Reduction in recruitment and control of dysequilibrium was followed by a trial of instrumentation. In a small proportion of Alzheimer's patients, SPECT abnormalities can be primarily unilateral and correspond with signs of unilateral functional disturbances found on neuropsychologic tests. Three major findings reported by Shenton and colleagues23 are (1) lateralized left-sided decrease in gray matter in the anterior hippocampus- amygdala, parahippocampal gyrus, and superior temporal gyrus with an associated increase in the temporal hom of the lateral ventricles; and (2) a strong correlation between the degree of thought disorder and decrease in volume in the left posterior superior temporal gyrus, a region previously acknowledged to be significant as a neuroanatomic substrate for language,24,25 and (3) a statistically significant correlation between volume reduction and neuroanatomically interconnected temporal lobe regions, which may be important in performing auditory associative memory links. A decrease in cognitive function was reportedly delayed years fol-lowing the onset of tinnitus in this patient. The clinical history of an associated memory disorder accompanying intensification in tinnitus may be reflected in the hypoperfusion of the temporal lobes. The identification of subtypes of a central type tinnitus await future identification of a neuropathologic correlate which can only be accomplished by the scoring of neurons in brain, ganglion cells in the organ of Corti, and other factors.
Tinnitus of the severely disabling type as demonstrated by SPECT imaging of the brain, may in some patients be a soft, and key symptom or sign of organic brain disease. Observations of simultaneous auditory brainstem responses with monaural stimulation in the tinnitus patient. Seventeen of the subjects initially presented to the clinic with a primary complaint of tinnitus, rather than hearing difficulty. All subjects were given instructional counseling, relaxation exercises including progressive muscle relaxation (PMR), deep breathing and guided imagery, and sleep suggestions. A more detailed explanation of the Zen programming is available.17 Subjects were advised to not adjust the Zen volume unless deemed necessary by environmental conditions. The number of sessions necessary to accomplish a successful outcome varied and was defined by a clinically significant reduction in THI and TFI scores, or achievement of a non-significant score (< 20 for the TFI or less than 18 for the THI) for two consecutive visits, as well as a subjective report that tinnitus awareness, or tinnitus disturbance, or quality of life was no longer an issue negatively impacted by the tinnitus. A reduction of 13 points is considered clinically significant on the TFI.21 The dashed line represents the 13-point benefit score considered clinically significant. This decrease may be related to the fact that subjects had their tinnitus distress reduced over time and no longer felt the need to use fractal tones and noise as frequently as they did during the first 2 months of sound therapy. Not unexpectedly, there was a trend for the subjects least affected at baseline to also show the least amount of improvement. This implies that, as resolution was achieved, subjects tended to utilize the Zen programs, particularly those containing noise (B and C), less frequently while increasing their reliance on amplification-only.
This point underscores the importance of offering multiple sound therapy options, such as a variety of fractal tone styles and adjustable bandwidth noises, to those patients (approximately 10% in this study) who may prefer acoustic stimuli other than fractal tones. And, I very much enjoy my time with students, both in the classroom and in casual after class discussions. All you hear is the muffled sound of the radio, and you can’t hear the sounds very clearly.
Other tinnitus symptoms can be someone humming a tune, a clock that is ticking loudly, or you hear someone that is whistling.
The main reason for this is because the symptoms may be leading to a further diagnosis and you will need to be examined much more than you have expected. Vibration of the balloon eye was recorded by a piezoelectric accelerometer, amplified and conditioned, and fed into a fast Fourier transform (FFT) for analysis.
The effect on the acoustic transmission of pressuring the brain during Valsalva maneuvers was determined from the eye vibratory response.
Earplugs were inserted binaurally, and the pinnae were covered with Sennheiser sound-attenuating headphones (Sennheiser Electronic Corporation, Old Lyme, CT) to reduce the effects of ambient noise (attenuation of ~25 dBA) on thresholds. Driving the skull at 250 Hz, the peak vibratory energy of the balloon eye was also at 250 Hz with spectral spread (above and below the driving frequency) of approximately 20 dB lower. The main effect was at approximately 35 kHz, the presumed mechanical resonant frequency of the eye20.
The results revealed responses in the normal range of bone conduction hearing, with the exception of the low frequencies owing to the ambient noise in the laboratory. The eye is as sensitive as the skull, opening up the possibility of another method of stimulating the inner ear through a fluid conduction mechanism.
Though this was discouraging, it was not unexpected in that brain and eye the volumes differ and there is no direct connection; however, the optic nerve can act as an acoustic coupler between the brain and eye because all share the same acoustic impedance, as reflected in tissue densities (Table 1)24.
At frequencies near the eye resonance, air conduction sound will also couple to the ear via the eye20, which may be the mechanism for hearing damage for ultrasonic noise exposure in young workers27-29, a matter that is addressed in current federal regulations30. The use of audiofrequency rather than ultrasound is preferred in determining ICP noninvasively, because audio equipment is readily available and economical.
In this way SPECT reflects local neuronal activity.9-11 The availability for SPECT of specific receptorbinding radio tracers, which bind at a specific particular site of lesion within the CNS, may thus be identified. Narrow band masking curves were performed and yielded Type IV distance curves ipsilaterally and contralaterally.
Laboratory work including complete blood count, sequential multiple Analyzer Computer (SMAC) 25, thyroid examination, fluorescent treponemal antibody (FTA)-all reported normal. Associated complaints included bilateral hearing loss, with left greater than right, bilateral ear blockage left worse than right, early memory dysfunction, and an occasional positional dysequilibrium.
The tinnitus patient may develop a memory not only for normal auditory stimuli but also, paradoxically, for the aberrant sound, that is, tinnitus. This report stresses that it is not known whether similar features are present in patients with other diagnoses such as mood disorders with psychosis or in patients with a first episode of schizophrenia, in whom the potentially confounding effects of chronicity and medication may not have occurred.
Neuropsychologic testing demonstrated inter-ference in cognitive function, which raises the question as to whether or not in this patient and in others with similar patterns of cortical asymmetry, the tinnitus may have such a medical significance. The overall aim of Widex Zen Therapy is to ensure that the tinnitus does not negatively impact the patient’s quality of life, as opposed to reducing the loudness level or production of the tinnitus. All but 7 subjects had experienced tinnitus for more than 1 year, and all but 4 reported tinnitus in both ears. Additional counseling in the form of cognitive behavioral intervention was applied when the clinicians believed appropriate.
Subjects who showed clinically and significantly improvements didn’t require all the planned sessions; however, the THI, TFI, and datalogging measures were still collected as planned. Symbols falling below the diagonal dashed line reflect clinically significant relief from tinnitus. The usage of Zen A (fractal tones) decreased somewhat, but this reduction was not statistically significant. A Measurement Specialties Incorporated (Hampton VA) model ACH-01 accelerometer recorded the vibration of the balloon eye. However, when the brain was pressurized, the energy peak at 250 Hz was 12 dB lower than the unpressurized condition, with damped frequency spread (25 dB lower).
Nonetheless, the average 250 Hz threshold was at 30 dB Hz and, for 500 Hz, was 9 dB higher. Further, the brain can be considered a closed-boundary condition with few compliant windows, whereas the eye has only a semibone boundary. These data all suggest that the brain can be a passive conductor of sound, even an amplifier near resonance20,31, and at the same time a physiologic responder to the sound propagated through it. Counting statistics for each ROI were derived by standard methods, and expressed as the mean number of counts. Associated complaints included ear blockage greater on left than on right, dysequilibrium, and cognitive and memory deficits. The vestibular test battery (computerized rotary chair and pursuit tracking test) was clinically interpreted as a primarily central oculomotor dysfunction; with a reduced vestibular response of the peripheral vestibular labyrinth right.
This is interpreted to indicate that although the tinnitus was maskable, an intensity level of at least 20 dB above the threshold would be needed to produce this effect.
For the affect component, psychiatric consultation for control of anxiety and depression included therapy with carbamazepine and clonazepam, with amitriptyline and flurazepam for sleep. A trial of Trental therapy for the central component was recommended for persistence of tinnitus.
15 It can be speculated that a short-term memory is established for tinnitus in the medial temporal-lobe memory system which becomes stored in associated areas of the neocortex.13,15 A paradoxical memory for tinnitus may cause the tinnitus to become clinically manifest as a severely disabling tinnitus. Namely, can be consider the presence of tinnitus, which precedes dementia, to be an early marker of aneurodegenerative disorder, with its initial focus in the primary auditory areas of the temporal lobe and tinnitus is the primary symptom? For most people that are affected by this disorder, the reactions can be seen by the movement of their eyes, shoulders, the tongue and the jaw. You have to really not take this lightly and just dismiss it as something that will just go away in time.
The accelerometer output was filtered, amplified, and fed into a Hewlett Packard dynamic signal analyzer Model 3561A (fast Fourier transform [FFT]) to quantify the vibration energy transmitted into the fluid-filled balloon "eye"; these values served as a baseline measurement for a nonpressurized balloon brain. Frequency changes were noted for almost all frequency regions below the eye resonance (35 kHz).
One thousand Hz was most efficiently transmitted through the eye with an average threshold of 0 dB HL. Thus, a positive pressure correlation is not necessary if, as in the present case, the acoustic response of the brain is reflected in the acoustic response of the eye, making a noninvasive measure possible. Significant past history included antecedent psychiatric history with hospitalization in 1986 and 1987 for depression, a sleep disorder stated by the patient to be related to tinnitus, and periodic marijuana use in 1970 to 1972. The neurotologic diagnosis was based on correlation of the clinical history, cochleovestibular test battery, neurotologic examination, and tinnitus evaluation identified tinnitus to be primarily of the central type with a cochlear component bilaterally, with left greater than right and a clinically presumptive secondary endolymphatic hydrops (SEH) on the left. In addition, 15 of the 19 subjects’ final TFI were below the 20-point score considered clinically significant.
Some of these sounds differ in pitch; some sounds can be of high pitch or low pitch depending on the intensity of the attack.
Sixty nine percent of these study patients suffered from pseudotumor cerebri, in which tinnitus is a common malady. The undriven frequency response of this model was the baseline condition, as depicted in Figure 3. In the simplest explanation, the IOP damps eye vibration at the resonant frequency (and partial frequencies) and it is that reduced amplitude that may correlate and possibly predict ICP.
The eye may have some advantages in delivering sound to the ear, but a prototype must be developed and tested for safety. Significant side-to-side count differences were determined by standard statistical analysis. Vestibular testing revealed a vertical upbeat nystagmus in all position tests with normal caloric testing.
In addition, it should be noted that the final mean TFI score was 11.76, a tinnitus distress score considered clinically insignificant. What you can do is to just submit yourself to the tests that the doctors will recommend for you so you can get a full grasp of what‘s really happening and eliminate these things right away. The lack of pressure correlation is unfortunate in that a patented technology is available to measure the acoustic resonance of the eye, employing amplitudemodulated ultrasound to determine IOP9. Markers were placed on the temporal bone, squamosal suture, and mastoid process, as well as on the occipital bone and frontal bone to maintain balloon position on repeated trials. 5) indicate that the bone conduction transducer sent energy through the fluids in the brain to the ears, as had been previously suggested12-14,20.
The intensity reduction observed in our study was dependent on frequency and varied from 4 to 12 dB. Additionally, patent-protected technology exists to measure ICP using ultrasound applied to the skull and eye10,11. Several audiometric frequencies (250-1,000 Hz) were applied to the bone transducer, and the accelerometer was placed at these locations to determine the resonance frequency amplitude. Maximal frequency response was found at the fundamental resonance of the eye (32-36 kHz) during Valsalva maneuver. After several trials, the condition of 250 Hz at 45 dB was observed to produce the best resonance patterns and was selected to be the input frequency for determining changes when the brain was pressurized. Static pressure (~5 Newtons) was applied to the back end of the balloon, resting in the cranium, pressuring the "eye" by the balloon skin threaded through the back of the orbit (ocular nerve foramen). Sinha and Wray9 measured the resonance of the eye at low frequencies and found biphasic peaks in the 280- to 310-Hz range, in agreement with the present findings (see Figures 2 and 3). The acoustic value was stable over the surface of the eye, in contrast to the well-reported variability on the skin over bone21, which has limited the clinical usefulness of low-frequency intracranial acoustic approaches10,11.
