Noise-induced hearing loss
Noise-induced hearing loss (NIHL) is hearing decrease caused by loud sound. Evidences of NIHL include a history of exposure to loud sound and a hearing loss in a narrow range of frequencies, such as those from gunfire, power tools, explosions and night club music. The loud sounds result in the over-stimulation of the hearing cells leading to cell death. The two types of loss are one, intense noise incident, or gradually, over time due to exposure to noise. There are certain fields in which workplaces have hazardous levels of noise. Musicians have a very acoustic ""workplace,"" and can develop gradual NIHL through the music they constantly hear. Governmental agencies describe workplace standards to manage noise pollution and protect the hearing of workers. The best, first option for protecting hearing is lowering the volume at the source of the sound. There are, however, ways to mitigate the damage after a period of potentially damaging noise. There are also options to manage hearing loss once it has occurred.While frogs, fish, and birds with hearing loss regain their hearing naturally, humans and other mammals do not.
