Does your audiometric monitoring program measure up?

All hearing conservation programs under CFR 1910.95 require audiometric monitoring. This article provides an overview of OSHA noncompliance citations related to audiometric monitoring and associated monetary penalties reported between January 1988 and June 1994. The data in this article reflect the degree of seriousness of different elements of noncompliance, because monetary penalties, at least empirically, are related to severity or importance of the element.

Noise levels in cockpits of aircraft during normal cruise and considerations of auditory risk.

Noise data, including A-levels and C-minus-A values, are summarized for exposures associated with normal cruise flight in 13 groups of 593 aircraft; means and standard deviations are reported; degrees of auditory risk using OSHA-1983 criterion are presented; and at-the-ear protected and unprotected exposures are revealed. Mean A-levels were 95.0 for 528 fixed-wing; 100.9 for 65 rotary-wing; and 95.7 for all 593 aircraft. Of 13 sub-groups, the lowest mean A-level (85.5) was exhibited in the cockpits of tail-mounted turbojet/fan-powered aircraft, and the highest (105.0) was found in both reciprocating and turbine-powered twin-rotor helicopters. All mean A-levels exceeded the OSHA damage-risk criterion for 8 h.d-1 exposures. At-the-ear exposures while wearing hearing protection are presented. Results clearly illustrate the potential for auditory damage of unprotected aircrews. Hearing protection must be considered to effectively control routinely encountered exposures. The material and illustrations resulting from this study will help health and safety monitors during indoctrination and counseling of aircrews concerning the need to protect their hearing against noise exposures during normal and routine flight operations.
