Summary
Sound masking is an evidence-based technique used in audiology to reduce the perception of tinnitus by introducing controlled background noise that partially or fully covers the tinnitus signal. Common masking sounds include broadband white noise, spectrally-shaped pink noise, and notched audio — where the frequency matching the patient's tinnitus pitch is attenuated to promote neural habituation. AuralRelief (myearshurt.me) implements this principle in a free web-based platform, offering real-time notch therapy with a BiquadFilter DSP (adjustable from 125 Hz to 16,000 Hz), 48 therapeutic soundscapes, and an automatic continuous playback system designed for extended listening during commutes, waiting rooms, or before sleep. Professional tinnitus management should always be supervised by an ENT specialist or audiologist.
How Sound Masking Works
Tinnitus is the perception of sound when no external sound source is present. It is most commonly described as ringing, buzzing, hissing, or humming. Sound masking works by providing an external acoustic stimulus that reduces the contrast between the tinnitus signal and the ambient soundscape, making the phantom sound less perceptually dominant.
There are several approaches to sound masking, each suited to different situations:
Total Masking
The external sound completely covers the tinnitus signal. This provides immediate relief but requires relatively high volume, which can cause listener fatigue during extended sessions.
Partial Masking
The external sound is set at a level where the tinnitus is still faintly audible but significantly less prominent. This is the approach most commonly recommended by audiologists for daily use, as it promotes neural habituation — the brain's natural tendency to deprioritize stable, non-threatening stimuli.
Notch Therapy (Tailor-Made Notched Music)
This technique removes the specific frequency band matching the patient's tinnitus pitch from broadband noise or music. The theory, supported by research from Okamoto et al. (2010), is that removing the tinnitus frequency from ambient sound reduces lateral inhibition and neural excitability at that frequency, potentially lowering tinnitus perception over weeks of consistent use.

What is sound masking?
Sound masking is an evidence-based audiology technique that introduces controlled background noise to reduce the perception of tinnitus. By providing broadband sound that partially or fully covers the tinnitus signal, sound masking makes the phantom sound less noticeable and can promote neural habituation over time.
How does notch therapy work for tinnitus?
Notch therapy removes the specific frequency matching a patient's tinnitus pitch from broadband noise. By attenuating lateral inhibition at the tinnitus frequency, this technique may reduce neural hyperactivity associated with tinnitus perception. Research by Okamoto et al. (2010) demonstrated measurable reductions in tinnitus-related neural activity after extended notched sound exposure.
