Noise-induced hearing loss (NIHL) and sound control standards for stone crushers

Abstract

Since globally industrial developments have utilized production machines, exposure to noise (any sound that may be hazardous to hearing) in workplace is inevitable. The same is true for Stone crushers manufacturer which is an important industrial sector in the Thailand. Therefore, the obvious measurement and criteria for sound control should be used in order to assess employee noise exposure, to prepare an effective noise reduction programmed and to protect the stone crushers workers from noise-induced hearing loss (NIHL). Legally, although there are hearing conservation program with periodic evaluations, health education about hearing mechanism and wearing personal protective equipment must be focused.
