The most common cause of hyperacusis is overexposure to excessively high decibel (sound pressure) levels, which can cause acoustic trauma. [1] An acoustic shock , which can lead to symptoms such as hyperacusis and ear pain, can also occur after exposure to an unexpected moderately loud to loud noise, even if this does not necessarily result in ...
Eustachian tube dysfunction can be caused by a number of factors. Some common causes include the flu, allergies, a cold, and sinus infections.

Their presence usually indicates an interstitial process, such as pulmonary fibrosis or congestive heart failure.

This injury can occur after exposure to a single, loud noise or from exposure to noises at significant decibels over a longer period of time. [medical citation needed] Many cases have included a period of reduced hearing after exposure to loud ...
