Epidemiological evidence for the effectiveness of the noise at work regulations
... men aged 65 with a history of exposure to an LEP,d of 90 dB(A) would have hearing threshold levels (HTL) at 4 kHz that are 20 dB greater than their non-exposed peers. Approximately half of this difference would have accrued in the first five years. Insofar as ISO 1999 gives a true indication of the ...

The value of these data has, of course, over the long time of subsequent studies with successive technical refinements, been placed in doubt. Békésy’s technique required the use of very loud sounds (>120 dB SPL) and it has since been clearly ...

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.
