an ear condition,in which one has a collapsed tolerance to normal environmental sounds,which normally would not bother a person with normal hearing's ears.certain sounds will cause your ear drums to cringe,and have a spasm which is described as "fluttering" in the ear drum.it can be more severe in some cases than others from what i understand.it is caused by a number of things,such as prolonged exposure to loud noise,prolonged use of certain drugs,such as aspirin,head trauma,and many others.all though there isn't exactly a total cure for it,the ear's tolerance level can be brought up greatly by using pink noise cd's.by doing so it can get alot stronger,and it will be able to tolerate more noise,but it will not make the ear 100% better.
i am 18 years old and already have hyperacusis,mainly cause i did the stupid thing by listening to music on headphones daily,for 8 years,played in a band that practiced significantly loud,and used aspirin for a long period of time,due to the fact that i thought i had a non-existant heart problem.DON'T MAKE THE SAME MISTAKES AS ME.

Get the hyperacusis mug.
A rare, debilitating hearing disorder that is characterized by an extreme sensitivity to sound. Normal sounds are perceived as too loud, while very loud sounds (such as a crowd cheering at a concert, or a very loud talker), are extremely painful and sometimes distorted.

People with hyperacusis also tend to have tinnitus as well, which worsens with loud sounds. Talk about a Double Whammy!

Hyperacusis often comes on suddenly, and it is not curable. However, it can be reduced to the point that it's barely noticeable.
"My mate has hyperacusis, and his mom talks so loud that I can hear her loud and clear all the way across the house. I can only wince at how painful it must be for him."
