Response of personal noise dosimeters to continuous and impulse-like signals
Abstract
A study of the capabilities of noise dosimeters to measure personal exposure to time varying and impulse-like noises was carried out. Ten commercial noise dosimeters were obtained. A laboratory reference noise dosimeter was constructed to provide a demonstrably accurate basis with which to compare the commercial noise dosimeters. Each commercial dosimeter, when ordered from the manufacturer, was specified to have a threshold A-weighted sound level of 80 dB, a criterion sound level of 90 dB, and an exchange rate of 5 dB and/or 3 dB. The performance of the commercial dosimeters was compared with theory and with results obtained from the reference dosimeter. Except in a few isolated cases, the commercial dosimeters were in general agreement with the performance specification of the appropriate American National Standard and with the Occupational Safety and Health Administration (OSHA) regulations.
