Forty hospitalized patients with sudden hearing loss and tinnitus were compared to a control group (N = 28) of inpatients of an ear-nose-throat ward. Certain single-case studies have reported the association between stress and SHL [9], as have some group studies that used qualitative interviews as assessment instruments [10,11].
From a physiological point of view, the assumption of the contribution of stress to the onset of SHL and TIN has some plausibility.
The main objective of the current study is to examine the association between stress SHL and TIN in a control group design, using a comprehensive and methodologically refined assessment strategy. Our study, therefore, tested the following assumptions: Onset of SHL and TIN is associated with a high level of stress defined by life events and daily hassles, habitual dysfunctional coping strategies, a high level of worrying, and a low level of social support. Because a prospective design relating to the stress hypothesis with hundreds of non symptomatic subjects was beyond our research capacities, a control group design was used. Daily hassles (DH) were assessed by the German questionnaire Alltagssorgen-Skala [33] (Cronbach's alpha = 0.96), which is based on the Daily Hassles Scale by Kanner et al. To determine the level of worrying (W), the German version of the Penn State Worry Questionnaire [36] (16 items; a 5-point rating scale) was presented to the subjects. The experimental subjects were contacted by telephone 3 months after they had been assessed for the first time. Patients with SHL and TIN show significantly higher scores on both measures of stress, on the life event scale, and on the daily hassles scale than those in the clinical control group.
As expected, significantly more negative coping strategies (COPneg) were found in the experimental group.
The prospective part of our study examined the connection of psychological test variables (LOCint, LOCpow, LOCfat and LE, DH, W, and social support), sociodemographic variables (age, gender, family status, number of children), and characteristics associated with the disorder (TIN in the past, acute TIN, disability due to TIN and SHL, and WB at the onset of the disorder), all measured at onset of the hearing disorder, to the chronicity of TIN and hearing loss 3 months later.
The chronicity of TIN is correlated most closely to WB at disorder onset, COPneg, and LOCfat (Table 5).
In a discriminant analysis, the six variables of all three categories (WB, COPneg, LOCfat, acute TIN, age, disability due to TIN) associated most highly with chronicity of TIN were used to separate the group of patients with TIN from recovered patients. Chronicity of SHL (n = 18 of 35 subjects) is associated most closely with WB at the onset of the disorder, with disability due to TIN and SHL, and with the degree of anxiousness concerning SHL and LOCfat. The six variables-WB, disability due to acute TIN, SHL, LOCfat, anxiety concerning SHL, and number of SHL-correlated most highly to the chronicity of hearing loss were entered into a discriminant analysis at the same time. The hypothesis regarding the stress differences expected between SHL and TIN patients and the control group before the onset of the disorder was confirmed fully. The affective state of certain persons often has been shown to influence memory; in a negative state, more negative memory contents are activated and retrieved.
At first glance, the data about worrying confirm our hypothesis that it is more intense in SHLITIN patients.
The discrimination analysis fully supported the foregoing conclusions, selecting daily hassles as the strongest variable in the prediction of group membership and coping as a further relevant aspect. The second part of our study was concerned with the prediction of chronicity of SHL or TIN 3 months after onset. Though the validity of these predictions cannot be guaranteed and has to be cross-checked, an interesting note is that the supposedly predisposing stress factors that seem important for the onset of the studied hearing disorders do not contribute to its chronicity. All in all, our study suggests that psychological variables related to stress and its processing are predisposing for TIN and SHL and that the actual subjective state of well-being shortly after onset of the di sorder is a relevant predictor of chronicity of both disorders.
Though our data support the hypothesis of psychological influences on disease etiology and prognosis in SHL and TIN, some methodological limitations of the study have to be taken into account. The intent of our study was to sample similar groups maximally except for the disorder itself. Furthermore, the conclusions drawn from the prospecti ve part of the study, especially regarding the importance of psychological variables, are somewhat uncertain.
Many researchers have investigated the possibility of using auditory evoked potentials (AEPs) to objectively diagnose tinnitus.
A reliable physiological measure capable of diagnosing tinnitus would be a valuable addition to the assessment and management of tinnitus patients. Auditory electrophysiological measures have been extensively studied in individuals with tinnitus to determine whether AEP results offer insight into the mechanisms of tinnitus perception. To further evaluate AMLR as a possible physiological measure of tinnitus, this study investigated whether increased AMLR amplitude is characteristic of individuals with severe tinnitus and hearing loss opposed to individuals who report no tinnitus, but have hearing loss. The current study's hypothesis was that individuals with severe tinnitus would reveal a pattern of enhanced AMLR amplitudes compared to a control group, consistent with the findings from Gerken et al. Tinnitus severity was quantified using the Tinnitus Handicap Inventory Questionnaire (THI) developed by Newman, Jacobson, and Spitzer (1996). Data were recorded using a Bio-logic (Natus Medical Inc., San Carlos, CA) Navigator Pro or Explorer measurement system installed on a desktop computer.
Absolute latencies of AMLR components were designated as the negative most amplitude point or highest positive amplitude point within the time domain of 16-25 ms for Na, 25-35 ms for Pa, 35-45 ms for Nb, and 50-80 ms for Pb (Jerger et al., 1988). The goal of the analysis was to determine if tinnitus affects AMLR latency and amplitude, after adjusting for known effects such as age, hearing ability, and gender. The AMLR mean vector was modeled using the multivariate response regression model, with an unstructured correlation among AMLR latencies and amplitudes measured on the same subject.
A multivariate response regression model was fit to the AMLR data, including tinnitus status, age, gender, and hearing ability as predictors.
The hypothesis that the AMLR would be sensitive to detect neurophysiological changes in the central auditory system secondary to tinnitus was not supported by data collected in the current study. Many factors contribute to the generation of AEP waveforms, such as neuronal firing rate and neuralsynchrony of AEP components (Eggermont, 2007). Published studies utilizing electrophysiological measures to evaluate tinnitus usually report differences in neural activity in individuals with tinnitus, but it is not possible to know to what degree concomitant factors contributed to the results. In summary, previous studies of auditory electrophysiology in individuals with tinnitus have shown prolonged latencies and enhanced amplitudes of AEP components. The data presented here represents a portion of the dissertation research conducted by Sarah Melamed Theodoroff at the University of Illinois, Urbana-Champaign. VA RR&D, National Center for Rehabilitative Auditory Research, Portland VA Medical Center, Portland, Oregon. Several prognostic indicators of favorable outcome in idiopathic sudden sensorineural hearing loss (ISSHL) have been proposed: an initial profound hearing loss, a downsloping audiometric curve, advanced age, and the presence of vertigo.
There is no agreement about the signs and symptoms that might predict a favorable prognosis in idiopathic sudden sensorineural hearing loss (ISSHL). Our study included 67 patients (37 male and 30 female) admitted to the department of otolaryngology of the Bnai-Zion Medical Center in Haifa between 1990 and 1997 owing to unilateral ISSHL. The correlation between high-tone ISSHL and poor prognosis was presented in a study by Linssen and Schultz-Coulon [4].

One presently prominent theory postulates that both disorders result from a diminished supply of blood to the inner ear, which impairs the inner and outer hair cells by lack of oxygen [1,5,10,22]. Stress is assessed by psychometrically validated inventories of life events and daily hassles. The study examines whether psychological predictors exist for maintenance of hearing loss and TIN 3 months after onset. The main guideline for the selection of the control group was to assess patients with maximal similarity to those in the experimental group of patients with SHL and TIN so as to rule out threats to internal validity, as addressed by Kazdin [29]. At the time of the assessment, all patients selected for the study were hospitalized in the ear-nose-throat ward.
Patients were on the average approximately 40 years old, and nearly one-half (48.5%) were female. The first questionnaire asked for sociodemographic data (age, gender, family status, number of children, profession), information regarding the circumstances of the disorder (both groups), and a detailed description of SHL and TIN (experimental group only). Stober [37] found a Cronbach's alpha of 0.86 for the German version of the Penn State Worry Questionnaire, which is similar to the Cronbach's alpha found by Molina and Borkovec [38].
This outcome is true for both aspects, the number and stressfulness of events (Table 3), though subjective strain differentiates more clearly between the groups.
However, in contrast to expectation, they also showed significantly more positive strategies (COPpos, see Table 3). This finding indicates that the lower the state of wellbeing, the higher is the probability of TIN maintenance.
The number of predictors is limited to six, as the number of subjects should not be less than the number of predictors multiplied by five.
Chronicity of hearing loss is not correlated to the other sociodemographic variables or characteristics attributed to the disorder (Table 6).
Life events and daily hassles before the onset of the disorder were significantly more frequent, and their stressfulness was more distinct in the experimental group. As a marked difference in well-being was found between the two groups (worse mood in the experimental subjects), the variance between groups attributed to differences in well-being was eliminated by partial correlation. The hypothesis of more COPneg strategies in the experimental group was supported, but the level of positive coping endeavors also is much higher in the SHLITIN group, a finding contrary to expectation.
However, after controlling for well-being, this effect vanished, which demonstrates that the process of worrying is intensified markedly by an individual's negative state.
The general assumption is that the probability of remission of these special hearing disorders at that time is rather low, so that a chronic state can be assumed.
The only psychological trait variable with some predictive power for TIN is negative coping.
Only habitual processing variables (coping, fatalistic LOC) show some influence on chronicity, but the best predictor is well-being, probably an indicator of the subjective evaluation of the biopsychosocial state of an individual.
Habitual psychological trait characteristics (coping, LOC) exhibit some, but not a strong, influence. The experimental group exists of patients suffering predominantly from both types of hearing disorders; very few persons were afflicted with TIN or SHL only. This was successful in nearly all assessed variables, with the exception of well-being, which turned out to be an important variable.
Published AEP studies suggest differences in neural activity in individuals with tinnitus compared to control groups, but the results are not consistent. There have been many attempts to develop objective measures of tinnitus, but to date, none have been successful. The generators of the early AEP responses are associated with the auditory nerve and brainstem, whereas the middle and late responses correspond to neural activity higher in the central auditory pathway such as the midbrain and cortex (Hall, 1992).


Tinnitus by definition involves the perception of sound in the absence of acoustic stimulation and is theorized to manifest in the central auditory system (Eggermont, 2003; Cacace, 2003). If results reveal this pattern of AMLR activity, a clinical application could be developed using AMLR to monitor tinnitus management. All research procedures were approved by the University of Illinois at Urbana- Champaign and Oregon Health & Science University Institutional Review Boards (IRB# 05356 & 2047 respectively).
In cases where the tinnitus was equally severe bilaterally, the test ear was chosen randomly. AMLR Waveform: Non-Tinnitus - Sample AMLR waveform recorded from a non-tinnitus participant.
If the waveform had multiple peaks or a broad plateau shape, the highest point in the middle of the plateau was marked. The observed AMLR latencies and relative amplitudes define a 6-dimensional response vector measured on each subject. The model included age, mean pure tone thresholds between .25 and 3 kHz, mean pure tone thresholds between 4 and 8 kHz as continuous covariates, and gender and tinnitus as categorical predictors. Absolute latencies (ms) of AMLR components Na, Pa, Nb, Pb and the relative amplitude (µV) of Na-Pa and Nb-Pb were analyzed to determine if group differences existed. Latency - Mean AMLR latencies (ms) are represented by black bars for the non-tinnitus group and by white bars for the tinnitus group. Amplitude - Relative AMLR amplitudes (µV) are represented by black bars for the non-tinnitus group and by white bars for the tinnitus group. Although participants with tinnitus in the current study were older and had more hearing loss than non-tinnitus control participants, AMLRs recorded from both groups were statistically similar.
In addition, age and hearing loss affect AMLR amplitude and latency in a well documented way, for example, Pa latency becomes delayed and amplitude sometimes enhanced with advancing age (Woods & Clayworth,within the same approximate age range. The AMLR protocol used in the current study elicited patterns of neuronal activation that were similar for subjects with or without tinnitus. However, without better replication of these results, to date no AEP measure offers consistent diagnostic capabilities for tinnitus.

It is believed that an initial profound hearing loss, a sloping hearing curve, vertigo accompanying the hearing loss, and advanced age predict an unfavorable prognosis [1]. The possible prognostic factors in ISSHL evaluated using multivariate analysis included age, gender, vertigo, electronystagmography results, time elapsed between onset of sudden deafness and beginning of treatment, mean speech frequency threshold on admission, and a word recognition test. No significant prognostic relationship was found with improvement of audiometric threshold over the speech frequencies. The correlation between vertigo and high-tone hearing loss is explained by the anatomical proximity of the basal coil of the cochlea and the vestibule. In our study, vertigo was found in 17 patients (27%), and we did not find any correlation between the presence of vertigo and the improvement of hearing at the various speech frequencies. The main objective of our study was to test the hypothesis of stress as a predisposing risk factor in the development of sudden hearing loss and tinnitus. Their pathophysiological features, the assumptions concerning their pathogenesis, and their medical treatment are rather similar [5-8]. Patients suffering from SHL (N = 98) reported more stress than did 13 patients with morbus Meniere who were used as control subjects. Vascular processes, mainly responsible for blood flow, are regulated by the sympathetic nervous system and the hypothalamic pituitary adrenal axis, the main systems activating cardiovascular stress responses.
Because external stressors have no direct influence on health but are mediated by subjective evaluation and processing of the stressful situation [23], habitual coping strategies also are studied. The variables examined as possible predictors are the same as those mentioned earlier as assessed at the time of the onset of the disorder. Additionally to the disorder itself being different in the control group, the disease should not be associated conceptually with stress in its etiology. Furthermore, patients rated their actual well-being (WB) on a 5-point scale from very good (5) to very bad (0). The 56 items reflect a variety of everyday hassles concerning work, household, marriage, money, friends, and family. The Streβverarbeitungsbogen assesses the likelihood of various habitual coping behaviors in situations leading to discomfort, arousal, or tension. The contacted subjects were interviewed about the status of their hearing disorder, especially whether their TIN or hearing deficit still were present. Also, the more negative coping strategies individuals exhibit and the stronger a fatalistic locus of control in individual patients, the more probable is the maintenance of TIN. Interestingly, the reported strain due to the stressful events differentiates more clearly between groups than does their number. Otherwise, the reported higher amount of stress could be ascribed to the negative state of those in the hearing loss and TIN group at time of assessment.
One can assume that the classification of coping behaviors into "bad" or "good" regarding their problemsolving or palliative capacity may be invalid, as some often have argued that the effectiveness of coping also depends on the kind of stressor and other characteristics of the situation. The discrimination between groups was well above chance but, with an error rate of 25%, was not really very satisfactory. Interestingly, this global self-evaluation is more important than is the rating of disability due to TIN and SHL and variables related to the history of the disorder. The definitely worse state of well-being in the experimental group points to the fact that the comorbidity of SHL and TIN probably is very stressing and annoying. Nevertheless, our data support the hypothetical role played by stress and related psychological factors in the etiology of SHL and TIN.

There is a great deal of variability seen in auditory evoked- and event-related potentials in the tinnitus population, which reflects AEP variability in general.
This view is consistent with the general finding that tinnitus sufferers display a high degree of variability on auditory electrophysiological measures.
Individuals undergoing treatment for their tinnitus or who had tried tinnitus treatments in the past were not excluded.
Each participant in the non-tinnitus control group was matched to a participant in the tinnitus group in regards to the test ear.
The relative peak to peak amplitude of the Na-Pa complex and Nb-Pb complex were computed from the voltage measured at the absolute latency of the AMLR components Na, Pa, Nb, and Pb. The AMLR mean vector denotes the vector of the means of these six elements (Na, Pa, Nb, and Pb latencies and Na-Pa and Nb-Pb relative amplitudes) indexed by tinnitus status. We tested the null hypothesis of no tinnitus effects on the AMLR mean vector using an F-Test with 6 numerator and 28 denominator degrees of freedom. Wave V of the auditory brainstem response was present in the recordings and was within the normal range for all subjects, suggestive of normal function in the neural auditory pathway preceding the AMLR. The sampling strategy of balancing on age and hearing loss helped to reduce confounding on these important effects.

Expanding the biological basis of tinnitus: crossmodal origins and the role of neuroplasticity. Vertigo accompanies ISSHL in 30-40% of cases and is considered to be a poor prognostic sign [1,2]. All patients underwent a complete audiological investigation, auditory brainstem response tests, electronystagmography, computed tomography of the brain and internal acoustic canals, and magnetic resonance imaging of the brain. Cochlear lesions may cause vestibular damage by endolymphatic alterations via ductus reuniens. We did find a statistically significant correlation between vertigo and the lack of improved hearing at 8 kHz. Thus, differences in life events and daily "hassles" were expected between groups, as were differences in coping styles, habitual worrying, and social support.
Quite a number of experts and laymen believe that the onset of SHL and TIN is mediated by stress.
However, no standardized measures were applied, and no quantitative statistical analysis of the data was conducted. What must be borne in mind, however, is the existence of various theories of pathogenesis and etiology of these hearing disorders; in general, all lack sound empirical support and somehow differ in their views of the functional role attributed to stress. Furthermore, worrying [24] is an important factor related to the processing of stressful information, a trait variable that has not yet been considered in regard to the onset of hearing disorders. Additionally, locus of control assessed at the same time is included as a psychological trait variable, which has been studied often in the context of chronic disease [25-28]. For the control group, inpatients suffering from different conservatively treated illnesses of throat, ear, and nose were selected.


Life events (LE) were assessed by the German version of the Social Readjustment Rating Scale (retest-reliability after 10 weeks, Pearson's coefficient, r = 0.71) [31,32]. Number and stressfulness of hassles during the last 4 weeks before the onset of the illness were assessed.
Wellbeing showing a significant difference between groups can be considered as a potentially confounding variable. Worrying had a significantly higher level in the experimental group, but this difference was lost after statistical control for well-being.
Thus, the subjective evaluation of stressful events is more important than is the sum of events.
However, the difference in stressfulness of life events and daily hassles were shown to be maintained at a significant level. Regardless, the fact remains that different coping behaviors, whether positive or negative, are used much more frequently by the experimental group. All subjects reported an extraordinary high degree of social support (high above the average of the norm group).
The most powerful predictor both for chronic TIN and for SHL is the state of subjective wellbeing at time of first assessment immediately after the onset of the disorders. Furthermore, what should be mentioned is that the explained variance is higher in the prediction of chronicity than in the discrimination of the different clinical groups. The search for prognostic factors of chronicity must be continued, after this first attempt offering some challenging data. In Bradley WG, Deroff RB, Fenichel GM, Marsden CD (eds), Neurology in Clinical Practice, Vol. At the present time, there is not a specific AEP measure able to objectively diagnose tinnitus. Results from these studies vary, and although group differences between individuals with tinnitus compared to those without tinnitus are sometimes reported in the literature, the findings often are not replicable. The non-tinnitus individuals served as a control group and the eligibility criteria were the same as above except adults needed to report no history of constant tinnitus. To achieve our goal of testing the effects of tinnitus on mean AMLR responses, we developed a multivariate response regression model of the AMLR mean vector as a function of gender, hearing ability, and age as well as tinnitus status.
The mean values for AMLR latencies and relative amplitudes are displayed in Figures 3 and 4 respectively. Changes in spontaneous neural activity immediately after an acoustic trauma: implications for neural correlates of tinnitus. Sixty-seven patients with ISSHL, aged 52 years on average, were treated with tapered doses of oral prednisone and complete bed rest. In 1975, Siegel [3] was one of the few who did not consider vertigo to be an unfavorable prognostic sign.
Imaging was part of the workup, with the purpose of excluding possible retrocochlear lesions, including demyelinating diseases. In 1993, Nakashima and Yanagita [5] studied 1,313 ISSHL patients and found that 30% had vertigo. On the basis of our results, we suggest that vertigo is not an adverse prognostic sign for the outcome of hearing, except in the case of high-frequency hearing loss.
The hypothesis of more frequent and more stressful life events and daily hassles was supported empirically.
Because of the abundant clinical evidence for the importance of stress, the simplified model illustrated in Figure 1 and derived from Hoffmeister [1] is used for the conceptualization of the presumed interplay of stressrelated somatic and psychological factors. Patients were asked whether any of the 42 given life events took place within the last year. It consists of three scales: internality (LOCint), powerful others-externality (LOCpow), and fatalistic externality (LOCfat). The group differences in both aspects of LE and DH, however, remain significant after statistically controlling for well-being (see Table 3). No difference was registered in the level of social support; both groups showed very high scores (Table 3). Our data show, as is found often in other studies, that life events and daily hassles are not independent of each other but correlate to a large degree. Thus, well-being had some effect on remembering and reporting negative events, especially on the number, but the difference between experimental and control group cannot be explained totally by their different state of well-being.
What might be posited is that the experimental group uses more coping strategies because they meet more life problems, as shown. Generally, social support may be very high in the special situation to which all subjects were exposed: being in the hospital for their first few days.
Also very influential is the degree of disability due to TIN experienced at first assessment.
One undesirable aspect of our study is the difference in the number of subjects in the experimental control group, due to the difficulty in recruiting control patients.
The auditory middle latency response (AMLR) has not been extensively examined to determine its potential as an objective measure of tinnitus; therefore, this study examined the AMLR in fourteen individuals with and without severe tinnitus to determine its potential as a diagnostic measure of tinnitus. The current study attempted to control for confounding variables through the statistical model employed. This approach is a natural extension of standard multiple analysis of variance (MANOVA) models to include continuous and categorical predictors, with the exception that we use restricted maximum likelihood estimation, as opposed to the method of moments, for inferences (Littell et al., 2000). The results from the current study did not reveal tinnitus to have a large enough effect to demonstrate differences in any portion of the AMLR. The purpose of our study was to investigate whether there is a correlation between vertigo and the outcome of ISSHL. Section 107, the material on this site is distributed without profit to those interested in receiving the included information for research and educational purposes. The dominant role of daily hassles, especially their stressfulness as a risk factor, was shown clearly. In a well-designed but unpublished study by Mtinzel and Sander (oral presentation), however, no differences in stress were found between a group of patients with SHL and those in a clinical control group. Additionally, they had to rate the subjective stressfulness (or strain) of each event on a rating scale from 0 to 100. To assess the relative importance of LE and DH, controls were applied for their common variance. A further assumption might be that they are trying hard to cope with stress most of the time but are not successful, as the reported strain by the events is higher in the experimental group. In the prediction of chronic SHL, both disability due to SHL and TIN at onset are important. The task of identification of patients for the study was allotted to the hospital staff, who then informed the psychologists of their potential subjects.
Of the many studies that utilized electrophysiological measures in individuals with tinnitus, limited information has been published on the auditory middle latency response (AMLR) in this population. There is relatively little overlap in average pure tone thresholds for these frequencies in this sample, with only one non-tinnitus participant above the mean threshold observed for tinnitus participants.
A portion of this work was presented at the Illinois Academy of Audiology Conference in Chicago, IL (January 2006) and the American Auditory Society Annual Meeting in Scottsdale, AZ (March 2007). The patients were discharged after 10 days of complete bed rest when the daily prednisone dose reached 40 mg. Mattox and Simmons [2] reported that a descending audiogram slope associated with vertigo was an unfavorable prognostic sign.
This selection criterion was used to reduce bias effects of memory on self-report measures [30].
The groups did not differ significantly in any of the sociodemographic variables (Table 2). After controlling for the effect of DH, the difference in LE between groups no longer was significant; on the other hand, after controlling for the effect of LE, the difference in stressfulness of DH was maintained (see Table 4). After this procedure, the discriminating function of life events, be it number or strain, was lost. Thus, their potentially exhausting coping endeavors could also contribute to onset of the hearing disorders.
Because the identification of potential control group patients was much more difficult than was the identification of SHLITIN patients and because of the fact that pending surgery excluded many patients from the control group, the recruitment of the control subjects was very time-consuming and less successful. This outcome suggests that this AMLR protocol may not be specific enough to detect neurophysiological changes associated with tinnitus. Gerken, Hesse, and Wiorkowski (2001) published one of the few studies to evaluate the AMLR in individuals with problemtinnitus. In the current study, self-reported etiology included noise exposure, sideeffect of medication, head injury, and sudden onset not associated with any event (see Table 2). Clinical recovery was estimated by contrasting the audiometric results at admission and those at discharge 10 days later. Wellbeing is the only variable differing significantly, with control patients feeling better than did the experimental subjects. On the other hand, daily hassles (especially their stressfulness) retain their differentiating function.
However, the number of subjects lies within the range of statistical demands (number of subjects = 5 × number of variables) [41].
The prospective part of the study aimed at the prediction of chronicity of sudden hearing loss and tinnitus (3 months after onset) by sociodemographic, psychological, and disease-associated variables. Patients who fulfilled the established criteria were informed about the study and then were given the questionnaires, which they were supposed to complete within 2 days.
Thus, what can be concluded is that life events probably give rise to various stressful daily hassles that undermine health status.
Values greater than or equal to the median of the group were considered significant with respect to improvement. The strongest predictor of chronicity was the degree of well-being at the time of first assessment (soon after disease onset). Consequently, our study applying psychological instruments of satisfying reliability and validity in a control group design confirms findings by Hoffmeister [1], Kropp and Rad [10], Stange [11], and Neuser and Knoop [12]. Only one person contacted in the experimental group and three in the control group refused to participate (see Table 2). Displayed in Figures 1 and 2 are sample AMLR waveforms from a non-tinnitus participant and tinnitus participant respectively. Single trials that were contaminated with the post-auricular sonomotor reflex or had a greater than 50% rejection rate were discarded.
