Clinical trials into spectrally notched audio therapy for tinnitus retraining


While there is no known cure for tinnitus, its symptoms can often be reduced and controlled with various treatments. Audiologists and ENT doctors may recommend diet or medication-based treatments for some users and, if you have been prescribed medication, you should always continue to follow your medical professional's advice. In order to supplement any tinnitus management regime, you may also want to consider audio therapy for its reported benefits. Below is just some of the research supporting the claims that spectrally-notched audio therapy can help to reduce tinnitus symptoms:

Other research


Through our work, we have also collected data on the spread of people's tonal tinnitus frequencies. The charts below update automatically as we gather more data daily.

As you can see below, there is a clear multi-modal distribution of dominant frequency prevalence among tinnitus sufferers, with 2 most popular peaks of tinnitus frequency at around 7 and 11.5 kHz.

The lower line provides more granularity, albeit at some cost to accuracy, by grouping people's tinnitus frequency to the nearest 750 Hz. Here we can see the 7 kHz peak seems to actually be a bimodal distribution with peaks close to 6.5 and 8 kHz. However, note the errors bars, marking the margin of error for this sample size (assuming 10% of the planet's population suffering some level of tinnitus accounts for the total 'population').

The chart below shows tinnitus laterality; that is, whether people's tinnitus presents in left, right or both ears. As expected, the majority of tinnitus cases are bilateral.

The chart below shows frequency groupings of tinnitus separately for left, right and bilateral tinnitus sufferers. Note that in the combined results, the prevalence of people with left-sided unilateral tinnitus around 9.5 kHz seems to be masking an underlying bilateral distribution in the frequencies experienced by bilateral tinnitus sufferers.

We will post more of our data here as we collect and process it. Last update:
