Abstract

Noise-induced hearing loss (NIHL) is viewed as the noise exposure levels related to an eight-hour working day (LEx, 8h) exceeding the occupational exposure limit (OEL) of 85dB(A), which can irreversibly damage sensory hair cells of the cochlea. NIHL refers to the sounds at some frequencies that are more hazardous than other frequencies. The use of A-weighted sound levels cancel these effects so that two sounds with the same dB (A) level have approximately the same hazard.
