Audiological management of noise induced hearing loss.

Noise-induced hearing loss (NIHL) has no specific of exclusive audiological signs. The disorder is identified on the strength of a high probability conclusion and as a result of an exclusion process. Because of frequent legal purposes, audiometrical data measured and analyzed have furthermore to be as accurate and reliable as possible. The paper outlines the whole procedure involved in the audiological assessment of noise-induced hearing loss considering different stages for: suspicion and identification, hearing threshold measurement, etiological and differential diagnosis, apportionment.
