Abstract

As an essential part of any hearing conservation program, noise exposure levels of workers are measured to assess their risk of hearing loss. Whenever the legal limit is exceeded (e.g., 85 dBA, 90 dBA, etc.), measures have to be done to eliminate or reduce the risk. To do so, work practices are re-examined, hearing protection is introduced and/or engineering controls are put in place to reduce noise levels, and consequently, noise exposure levels. This paper presents a process by which several indices are calculated using the average noise exposures of the different work groups (LTrade) (e.g., 85-90 dBA, 90-95 dBA, etc.). The indices calculated using this method can be used in isolation or combined, so that a more complete picture (more representative rating) be obtained
