By listening to broadband noise at soft levels for a disciplined period of time each day, some patients can rebuild (i.e., re-establish) their tolerances to sound. [ 2 ] [ 47 ] [ 48 ] [ 49 ] More research is needed on the efficacy of sound therapy techniques when hyperacusis is the primary complaint, rather than a secondary symptom, indicating ...
Misophonia (or selective sound sensitivity syndrome) is a disorder of decreased tolerance to specific sounds or their associated stimuli, or cues.These cues, known as "triggers", are experienced as unpleasant or distressing and tend to evoke strong negative emotional, physiological, and behavioral responses not seen in most other people.

Noise-induced hearing loss (NIHL) is a hearing impairment resulting from exposure to loud sound.People may have a loss of perception of a narrow range of frequencies or impaired perception of sound including sensitivity to sound or ringing in the ears. [1]
