Tinnitus (ringing in the ears) is the perception of a sound without an external source and it is experienced by 10% of the world’s population, an estimated 600 million people. There are many factors that have been associated with an increased risk of developing tinnitus. What is the trigger that causes tinnitus to develop in some people with hearing loss but not in others?
Another hypothesis is that tinnitus develops because of changes in how the brain processes sound in response to altered input from the cochlea. The treatment works by inserting small acupuncture needles into your skin on specific points on your body.
In order to obtain complete cure, you have to find acupuncturists who are professionally certified and trained.
Acupuncture works towards healing the root cause of the illness and not only provides superficial relief from the condition for the time being. Adults and children can safely undertake acupuncture treatment to get relief from tinnitus. The traditional Chinese medicine is not only useful in treatments, but also ensures wellness after curing tinnitus.

More than 25% of the people who suffer from tinnitus obtain acupuncture treatment from trained professionals as the treatment proves to be beneficial. In order to cure tinnitus completely, our experienced acupuncturists identify acupuncture points, which needs to be stimulated depending on your body condition. Many patients with acute tinnitus report that western medication is not useful at all even in the beginning, as they are ineffective. However, if the root cause, which causes tinnitus, is identified and cured, you can get complete relief from the annoying condition.
So that you can get customized treatment, which will prove to be highly effective in treating tinnitus in the long run, rather than providing temporary relief. Questionnaires such as the tinnitus handicap inventory, tinnitus handicap questionnaire and mini-tinnitus questionnaire are often administered to gauge its emotional severity, degree of annoyance, disability, sleep disturbance and social impact.

Powerful, new structural and functional brain imaging techniques have proved useful in identifying regions of aberrant neural activity in the human central nervous system that appear to be linked to tinnitus.
While several other methods have been suggested as objective measures of tinnitus in humans, [15],[16] none of these have gained widespread acceptance as objective measures that can be used to assess tinnitus in individual subjects.Auditory neuroscientists have attempted to develop behavioral and electrophysiological methods for objectively assessing tinnitus in animals.
The background noise remains on continuously for 50% of the trials in a session, but on the other half of the trials, a brief (50 ms) silent interval (gap) is inserted into the ongoing background noise 100 ms prior to the onset of the startle stimulus.
The fact that the gap deficit was present at the low frequencies raises questions about the frequency specific nature of the GPIAS paradigm and raises questions about whether the tinnitus is "filling in" the silent gap in the background noise.If the hypothesis that tinnitus "fills in" the silent intervals in the background noise is correct, then subjects with tinnitus should show an impaired ability or should be unable to detect silent intervals in NBNs tuned to the pitch of their tinnitus. Conversely, these same subjects should be able to detect silent gaps in NBNs presented above or below the tinnitus pitch because the phantom sound of tinnitus is spectrally different from their tinnitus. To test this hypothesis, we evaluated 13 subjects with tinnitus (mean age 50 years) and varying degrees of HL and compared their results to 13 normal hearing subjects without tinnitus.
Long duration silent gaps (50 ms) were employed to match previous animal and human studies and to minimize temporal acuity deficits as a source of impaired performance in the hearing impaired subjects. The research project and recruitment notices were approved by the Institutional Review Board at the University at Buffalo and the research was carried out in accordance with the Declaration of Helsinki and National Institutes of Health (NIH) guidelines. Participants were informed about the nature of the study and signed a consent form prior to beginning the project. Inclusion criteria for the tinnitus group included the presence of tinnitus for more than 3 months and the ability to perform the hearing tests. Exclusion criteria consisted of (1) tinnitus patients with intermittent and fluctuating tinnitus or (2) if the intensity of the NBN stimuli presented at 15 dB sensation level (SL) exceeded the limits of the audiometer or exceeded the subject's loudness discomfort level.
The tinnitus group consisted of nine males and four females with a mean age of 50 years of age. The non-tinnitus group consisted of four males and nine females with a mean age of 24 years of age.
Audiometry Air conduction and bone conduction thresholds were measured in an audiometric sound booth using a Grason Stadler (GSI)-61 audiometer and standard audiometric procedures. Gap stimuli One-third octave wide, NBN (one-third octave intervals, center frequencies from 1,000 to 16,000 Hz) of 90 s duration were generated digitally (NCH tone generator, V 2.00) and stored on the hard disk of a personal computer. Subjects were first instructed to select the NBN that most closely matched the pitch of their tinnitus.
Then the NBN was presented at a comfortable listening level to the ear contralateral to the subject's tinnitus. Pairs of pseudo-randomly selected frequencies of NBN were presented on each trial and the subject was asked to report, which one was closest to their tinnitus.
After a series of iterative comparisons (15-20 pairs), the tinnitus pitch was defined as the center frequency of the NBN that most closely matched the tinnitus percept on three consecutive trials. After determining the tinnitus pitch, the intensity of the NBN was varied using standard audiometric (1 dB steps) procedures to determine the threshold of the NBN at the frequency of the tinnitus pitch match. Once threshold was determined at the tinnitus frequency, the subject was instructed to match the intensity of the NBN so that it was equal in loudness of their tinnitus. The NBN stimulus was presented to the tinnitus ear and gradually increased or decreased in 1 dB steps until the subject matched the intensity of the NBN to the loudness of their tinnitus. Tinnitus loudness was defined as the intensity that matched the loudness of the tinnitus on three consecutive trials. Thresholds were also determined for NBN presented one octave above the tinnitus pitch and one octave below the tinnitus pitch.
The pitch matching data from the tinnitus subjects were evaluated to identify the most common pitch matching frequencies (modes) among the 13 subjects with tinnitus. For the subjects with tinnitus, the NBN gap stimuli were presented at the tinnitus frequency, one octave above the tinnitus frequency and one octave below the tinnitus frequency. NBN gap detection performance was evaluated when the NBN gaps were presented to the tinnitus ear as well as the contralateral ear. Because some tinnitus subjects had very high thresholds, the NBN gap stimuli could not be presented at 15 dB SL at the designated test frequencies. Consequently, in the right ear, NBN gap detection was assessed 1-octave below, 1-octave above and at the tinnitus frequency in 11, 11 and 12 subjects respectively. In the left ear, NBN gap detection was assessed 1-octave below, 1-octave above and at the tinnitus frequency in 11, 10 and 11 subjects respectively. The false positive response interval was ~54 s (90 s stimulus minus 18 2-s NBN response intervals).
Hearing thresholds in the subjects with tinnitus were typically higher than non-tinnitus subjects. Thresholds above 2 kHz generally increased with frequency rising to 60-80 dB HL for most subjects.

However, a few subjects had thresholds <20 dB HL at most frequencies while one had thresholds between 80 and 100 dB HL. Despite the fact that the NBN were only 15 dB above threshold, mean (+standard error of mean [SEM]) percentages of gaps detected in the NBN were quite high in the subjects with tinnitus ranging from 81% to 94% in the left ear and 85-92% in the right ear. Results shown for NBN presented to the left ear (a) and right ear (b) of tinnitus subjects and left ear (c) and right ear (d) of no-tinnitus subjects. Mean (SEM, n = 13) gap performance ranged from 91% to 99% in the left ear and from 87% to 99% in the right ear.
To overcome this limitation, we compared the mean performance of tinnitus subjects (above, below and at the tinnitus frequency) with the mean performance of no-tinnitus subjects at 1, 8 and 12.6 kHz. Scatterplot showing the percent correct detection of 50 ms gaps versus dB HL in the left ear (c) and right ear (d) of tinnitus subjects. Data and linear regression lines are shown for frequencies 1-octave below, 1-octave above and at the tinnitus frequency. Significant values for the regression analysis are shown in the legend of each panelClick here to view NBN detection and HL HL is known to impair gap detection performance; however, the effects of HL are predominantly seen with very short duration gaps and presumably exert little or no impact on long duration gaps such as those employed here and in animal studies utilizing GPIAS to test for tinnitus. Data obtained above, below and at the tinnitus frequency of the left ear and right ear were subjected to linear regression analysis as shown in [Figure 3]c and d. The GPIAS paradigm has been frequently used in auditory neuroscience to obtain evidence of tinnitus in animals [24],[25],[28],[30] and more recently a modified gap-startle paradigm was used to test for tinnitus in humans. Evidence from some animal studies has suggested that the "filling in" of the gap often spans several test frequencies, whereas others have shown that GPIAS impairment is limited to a narrow range of frequencies associated with noise induce tinnitus.
Presumably, if the spectrum of the background noise containing the gap matches the pitch of the tinnitus, then the ability to hear the silent interval (gap) is impaired. Moreover, gaps in NBN that no longer inhibit the startle response are used to index the pitch of the subject's tinnitus. In contrast, a silent gap embedded in a NBN located above or below the tinnitus pitch should not inhibit the startle response as has been reported in some of the animal studies. Here, we tested this hypothesis by asking subjects if they could detect silent gaps embedded in NBN located above, below or at the tinnitus pitch. These results indicate that even when the spectrum of the NBN was near the tinnitus pitch and the patient was experiencing tinnitus the "gaps" were readily detected. Taken together, these results suggest that with the gap stimuli employed in our study, which were similar to those used in previous human and animals studies, the phantom sound of tinnitus did not simply fill in the silent interval as previously hypothesized by ourselves and others. This near-ceiling effect in gap performance may have made the detection task insensitive to slight differences in performance between tinnitus and no-tinnitus subjects. The ceiling effect in gap performance could be minimized by reducing the duration of the gap. In contrast, advocates of GPIAS emphasize the use of long duration gaps in order to rule out impaired temporal resolution as a confounding factor in GPIAS tests of tinnitus.
A final cautionary note is that our moderate samples sizes (n = 13) may have been underpowered to detect slight differences in performance between tinnitus and non-tinnitus subjects or performance differences at the tinnitus frequency versus NBN located 1-octave above or 1-octave below the tinnitus frequency.
GPIAS and gap detection The present results highlight a discrepancy between gap detection and GPIAS performance.
One possible explanation for the lack of correspondence between gap detection and GPIAS is that the former is a perceptual task involving attention, [40] whereas the latter is a sensorimotor gating phenomenon that presumably involves pre-attentive filtering of sensory stimuli. Detecting a 50 ms gap presented at 40-55 dB SL would be substantially easier than detecting a silent gap presented at 15 dB SL.
In either case, gap detection was not impaired near the tinnitus frequency.Another acoustic factor to consider is the bandwidth of the NBN. The one-third octave band NBN used in our human study are identical to those used in GPIAS studies of tinnitus in mice [46] and similar in bandwidth to the low frequency NBN used for GPIAS testing in rats.
Although our subjects were able to match the NBN to the pitch of the tinnitus, the perceptual characteristics of the NBN could be still be different enough from the perceptual characteristics of the subject's tinnitus to make it easily detectable [Table 1] (hissing, buzzing, ringing). These subtle perceptual features may be unavailable to animal subjects during the GPIAS testing.
Because the NBN used in this study were presented at a very low intensity (15 dB SL), spectral cues would likely be of little or no value because they would be at or below the threshold. However, spectral cues might play a more important role in GPIAS because the NBN are presented at higher SL than those used here.
HL and gap detection HL has long been known to impair temporal resolution and the detection of very short duration gaps at low SL levels. Detection of the 50 ms gaps decreased slightly with increasing HL indicating a slight effect of HL on gap performance [Figure 3]c and d. Gap detection was slightly poorer (9%) in the left ear of tinnitus subjects with HL than normal hearing subjects [Figure 3]a, but no differences were seen when comparing results from the right ear [Figure 3]b. While a small left ear difference was seen between tinnitus and no-tinnitus subjects, this difference could be due to HL [Figure 3]c and d and the fact that these Tinnitus subject were tested at different frequencies than the no-tinnitus subjects [Figure 2]a and b vs. The key point of [Figure 2]a and b is that tinnitus subjects were able to detect the gaps the vast majority of the time at the tinnitus frequency and there was no significant performance difference between the tinnitus frequency and frequencies above or below this frequency. These results are consistent with previous data showing that salicylate and noise induced HL do not significantly interfere with the detection of long duration gaps such as the 50 ms gap used in this study. A more robust experimental design would be to match each tinnitus subject with a no-tinnitus subject in terms of HL and then to test gap performance in the no-tinnitus subject at the same frequencies used for the tinnitus subject. Such a comparison would avoid the confounding effects of HL and frequency mismatch as occurred in [Figure 2]a and b versus [Figure 2]c and d.
We tested the "fill in" hypothesis in human subjects with tinnitus using gap detection stimulus parameters similar to those employed in previous animal and human studies and found that our tinnitus subjects were able to detect the silent gaps regardless of whether the NBN was above, below or near the tinnitus frequency. Thus, with stimulus parameters similar to those used in animal and human studies, we found that tinnitus does not simply "fill in" the silent intervals embedded in the background noise. This raises the possibility that the underlying perceptual processes that mediate the detection of gaps in NBN may be different from those involved with gap-inhibition of the startle response in GPIAS paradigms.
