Occupational Noise Exposure |

|
Prior to promulgation
of the HCA,
the existing Occupational Noise Standard (29 CFR 1910.95(a) and (b)) established a
permissible noise exposure level of 90 dBA for 8
hours and required the employer to reduce exposure to that level by use of feasible
engineering and administrative controls. In all cases in which sound levels exceeded the permissible exposure, regardless of the use of hearing-protective devices, "a continuing, effective hearing conservation program" was required. However, the details of such a program were never mandated. Paragraphs (c) through (p) of the HCA replaced paragraph (b)(3) of 29 CFR 1910.95 and supplemented OSHA's definition of an "effective hearing conservation program." |
