Tinnitus masker The ear has a resonance frequency (highest frequency response) at 3,000hz and rolls off at a very steep 26db/octave on the high frequency side. Unfortunately, most tinnitus is associated with hearing loss, and most hearing loss and tinnitus is high frequency. Most maskers are limited to about 6khz of effective output. Higher frequency output results in increasing distortion, and may cause rejection of the device. The minimum masking level (MML) is the minimum amplitude of narrowband noise centered on the tinnitus pitch (or frequency range) necessary to completely mask the tinnitus. Tinnitus maskers are commonly used by tinnitus sufferers when
Tinnitus retraining therapy since onset, recognition of tinnitus attenuation by sound generator, lower hearing thresholds (i.e. better hearing), high Tinnitus Handicap Inventory (THI) score, and positive attitude toward therapy. Despite the fact that there haven't been any recent studies which concluded in its optimal treatment, tinnitus retraining therapy has been applied to treating hyperacusis, misophonia, and phonophobia. There is no evidence that TRT or any other treatment can eliminate or decrease tinnitus. Tinnitus is a symptom, not a disease. As such, the optimal treatment strategy should be directed toward eliminating the disease, rather than simply alleviating the symptom. More than half of people
