Noise-induced hearing loss (NIHL) is a hearing impairment resulting from exposure to loud sound. People may have a loss of perception of a narrow range of frequencies or impaired perception of sound including sensitivity to sound or ringing in the ears . [ 1 ]
Noise-induced hearing loss affects adults and kids alike. This condition develops when damage occurs to the delicate hair cells in the inner ear due to exposure to loud sounds or noises. Get more ...
Noise-induced hearing loss is a permanent shift in pure-tone thresholds, resulting in sensorineural hearing loss. The severity of a threshold shift is dependent on duration and severity of noise exposure. Noise-induced threshold shifts are seen as a notch on an audiogram from 3000 to 6000 Hz, but most often at 4000 Hz. [16]
Often interventions to prevent noise-induced hearing loss have many components. A 2017 Cochrane review found that stricter legislation might reduce noise levels. [108] Providing workers with information on their sound exposure levels was not shown to decrease exposure to noise. Ear protection, if used correctly, can reduce noise to safer levels ...
Noise-induced and age-related hearing loss are the most common forms of hearing loss seen in adult patients and they often co-exist in the same patients. In collaboration with M. Charles Liberman and other researchers, Kujawa has examined the vulnerability of the synapses that connect hair cells in the cochlea to auditory nerve fibers.
If you have experienced noise-induced hearing loss, there is, unfortunately, no medical treatment to reverse the damage. However, you can prevent further damage by using hearing protection and ...
