Dear Mr. DeFao:
This is in response to your inquiry of December 7, 1981, regarding interpretation of the Hearing Conservation Amendment to OSHA's noise standard, 29 CFR 1910.95.
While it may be more difficult to track the noise exposure of some because of their mobility in their jobs, no employee is to be excluded from the hearing conservation program because of intermittent or variable exposures. In arriving at each employee's exposure, employers may use any approach involving measurements or calculations that are considered appropriate. Compliance with the 8-hour, time-weighted average 85 dB exposure level is determined through the integration of all continuous, intermittent and impulsive sounds between 80 dB and 130 dB.
The use of averages in determining noise exposures may exclude from the program some employees who should be included. In enforcing the standard, OSHA will use monitoring to determine whether employers have failed to include in the hearing conservation program all employees whose exposure equal or exceed a TWA of 85 dB. In addition, since employees covered by the hearing conservation program must be given an annual audiometric test, your present program may not meet this frequency in all cases where audiometric tests are required.
We hope you will find this information helpful. If you have any further questions, please do not hesitate to contact us.
