Abstract
Noise-induced hearing loss (NIHL) is one of the major occupational hazards. Several standards are currently available that stipulate the safety limits for noise exposures. While these standards are generally effective, this review highlights results from recent laboratory studies that show that these standards share certain limitations. For instance, they do not cover impulse/impact noise exposures satisfactorily. Likewise, they do not have provisions to account for interaction of noise with other agents, such as chemotherapeutic agents or industrial solvents. In addition, results from studies on susceptibility to NIHL are presented which suggest that an individual's susceptibility to NIHL can be moderated by prior noise exposures. Areas of potential interest for future research on NIHL are also identified.
