<unk>  is an injury to the inner ear that's often caused by exposure to a high-decibel noise. This injury can occur after exposure to a single, very loud noise or from exposure to noises at significant decibels over a longer period of time. Many cases have included a period of reduced hearing after exposure to loud sounds. Examples include after a concert or a visit to a discotheque or having worked with noisy equipment. This kind of hearing impairment is often temporary. After some recovery time, the<unk>  often will stop.
