Noise-induced hearing loss (NIHL) is hearing impairment resulting from exposure to high decibel (loud) sound that may exhibit as loss of a narrow range of frequencies, impaired cognitive perception of sound or other impairment, including hyperacusis or tinnitus. Hearing may deteriorate gradually from chronic and repeated noise exposure, such as loud music or background noise, or suddenly, from an acute, high-intensity noise incident including gunshots and use of loud horns or bursting of crackers or explosives. Individual susceptibility towards noise There appear to be large differences in individual susceptibility to NIHL.
The following factors have been implicated: ---Bad acoustic reflex in some people ---Noise exposure early in life ---Poor general health like heart problem, hypoxia, and Hyperviscosity syndromes, smoking and alcohol abuse. ---Type 2 Diabetes. Types of Noise-Induced…
