Noise and Hearing Conservation
The Occupational Safety and Health Administration (OSHA) regulates occupational exposure to excessive noise. The OSHA Action Level for occupational noise is 85 decibels (dBA) for an 8 hour day, with a permissible exposure limit (PEL) of 90 decibels (dBA) for an 8 hour day.
Safety and Compliance assists employees and departments in measuring workplace noise exposure, provides guidance for the Hearing Conservation Program, and advises in the selection of hearing protection devices and engineering solutions.
The Hearing Conservation Manual gives detailed information. The Noise & Hearing Conservation Fact Sheet provides a quick overview.
Hearing Conservation regulations are found at http://www.osha.gov, 29 CFR 1910.95. The regulations are provided in "Noise and Hearing Conservation."
The Centers for Disease Control and Prevention provides additional information at Noise and Hearing Conservation.
