Noise-Induced Hearing Loss

Noise-Induced Hearing Loss is a hearing impairment resulting from gradual or sudden exposure to loud sound.

Overstimulation of hearing cells can lead to permanent injury and dysfunction. As a rule, when hearing ability is lost in this way, hearing cannot be restored.

Noise-Induced Hearing Loss typically presents itself as a loss of perception of certain frequencies or by an overall reduced perception.

Hearing may deteriorate progressively because of chronic and repeated noise exposure, such as loud music, sporting events, or background noise in a factory (Occupational Hearing Loss), and so on.

Noise-Induced Hearing Loss may also come about suddenly from, for instance, a gunshot nearby or explosion.
