Noise-Induced Hearing Loss

Last updated 2 years ago

A number of individuals are affected by noise-induced hearing loss. In fact, research by the National Institute on Deafness and Other Communication Disorders shows that approximately 15 percent of Americans between the ages of 20 and 69—or 26 million individuals—suffer from high-frequency hearing loss which may be the direct result of over-exposure to loud noise.

Causes of Noise-Induced Hearing Loss

There are tiny hair cells located within the inner ear that are responsible for converting sound energy into electrical signals. These signals are then sent to the brain and interpreted as sounds. Isolated sounds that are too loud and continuous exposure to loud noises can damage these hair cells, resulting in noise-induced hearing loss, or NIHL. Isolated sounds that emit between 120 and 150 decibels, such as explosions from firecrackers and small firearms, and repeated exposure to sounds at or above 85 decibels may lead to NILH.

Symptoms of Noise-Induced Hearing Loss

Exposure to a single intense noise can lead to immediate hearing loss which is usually accompanied by tinnitus, or a ringing in the ears. This hearing loss may be permanent, while the symptoms of tinnitus may subside over time. Damage to the inner ear from continuous exposure to loud noises tends to occur gradually, but can still lead to tinnitus and hearing loss. Individuals who are developing NILH from continuous noise exposure may have difficulty understanding others and feel like others are mumbling, even when they are speaking clearly.
