A cause is traumatic noise exposure that damages hair cells in the inner ear. [33] Some evidence suggests that long-term exposure to noise pollution from heavy traffic may increase the risk of developing tinnitus. [34] When there does not seem to be a connection with a disorder of the inner ear or auditory nerve, tinnitus can be called "non-otic".
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 ...

Unsafe levels of noise can be as little as 70 dB (about twice as loud as normal conversation) if there is prolonged (24-hour) or continuous exposure. 125 dB (a loud rock concert is ~120 dB) is the pain level; sounds above this level cause instant and permanent ear damage. [citation needed] Noise and ageing are the primary causes of presbycusis ...
Additionally, in fully developed Ménière's disease, the balance system (vestibular system) and the hearing system of the inner ear are affected, but some cases occur where EH affects only one of the two systems enough to cause symptoms. The corresponding subtypes of the disease are called vestibular Ménière's disease, showing symptoms of ...
