 Noise-induced hearing loss, NIHL, is a type of hearing impairment caused by prolonged exposure to loud noises. It is a serious issue in many industries, where employees may be exposed to excessive levels of noise. The effects of NHL include decreased concentration, fatigue, headaches, sleep disturbances, and even complete hearing loss. To protect against these effects, employers should implement hearing conservation programs, HCP. These programs involve regular audiometric testing, providing hearing protection devices, and educating employees about the risks associated with noise exposure. HCPs can help reduce the risk of NIHL and its negative consequences. This article was authored by February Andrew Booty, Sadiowon.
