It's a Noisy Planet. Objective: Most of the Chinese occupational population are becoming at risk of noise-induced hearing loss (NIHL). NIOSH also recommends a 3 dBA exchange rate so that every increase by 3 dBA doubles the amount of the noise and halves the recommended amount of exposure time. The eardrum separates the outer ear from the middle ear, creating a barrier that protects the middle and inner areas from foreign objects. There are several occupations in which noise levels exceed 85 dB(A) on a regular basis which can lead to NIHL. Operating noisy machines during shifts when fewer people are exposed. An overview of occupational noise-induced hearing loss among workers Nevertheless, individuals with non-NIHL, such as presbycusis, may have hearing threshold levels in excess of these values. This kind of NIHL can be immediate and permanent. Regardless of how it might affect you, one thing is certain: noise-induced hearing loss is something you can prevent. Goley GS, Song WJ, Kim JH.
