Hyperacusis

Hyperacusis is a debilitating hearing disorder where there is an increased sensitivity to certain frequencies and volume ranges of sound. Everyday sounds can be unbearable to the sufferer but will have no effect to others. Hyperacusis is often accompanied by Tinnitus. Hearing loss is a major risk with both conditions.

Prevalence
Hyperacusis and Tinnitus have a prevalence of about 10–15%.
