See also "Occupational Noise". When the noise in a work area exceeds a TWA (time-weighted average) of 85 dBA, it is often necessary to require that workers be supplied with hearing protection devices (HPD) and eventually to reduce noise exposure by acceptable means. It is also necessary to establish a hearing conservation program (HCP). For noise exposure reduction, most situations call for consideration of the endurance and frequency of noisy tasks, to increase the distance from noisy equipment, or to place a sound barrier between the worker's ears and the noisy equipment, or eventually to replace or modify (quiet) the noisy equipment. We can integrate these four approaches for optimal solutions to your problem.
If you have acoustical or noise control design problems you would like to discuss, feel free to call or FAX us any time.
