Occupational Noise: Auditory and Non-Auditory Consequences

Adam Sheppard et al. Int J Environ Res Public Health. .

Abstract

Occupational noise exposure accounts for approximately 16% of all disabling hearing losses, but the true value and societal costs may be grossly underestimated because current regulations only identify hearing impairments in the workplace if exposures result in audiometric threshold shifts within a limited frequency region. Research over the past several decades indicates that occupational noise exposures can cause other serious auditory deficits such as tinnitus, hyperacusis, extended high-frequency hearing loss, and poor speech perception in noise. Beyond the audiogram, there is growing awareness that hearing loss is a significant risk factor for other debilitating and potentially life-threatening disorders such as cardiovascular disease and dementia. This review discusses some of the shortcomings and limitations of current noise regulations in the United States and Europe.

Keywords: continuous equivalent level; dementia; hidden hearing loss; hyperacusis; occupational noise exposure; otoacoustic emissions; sound pressure level; tinnitus; ultra-high frequency.
