Occupational noise measurement standard: ANSI S12-19

Abstract

This standard provides procedures for the measurement of occupational noise exposure from all types of noise; e.g., continuous, fluctuating, intermittent, and/or impulse/impact. Measurements may be reported as sound level with corresponding duration, time-weighted average sound level, and/or noise dose. This standard provides for the measurement of the noise exposure of individuals and can be extended to represent groups performing similar activities. It can also be used to measure the noise exposure from a given job or activity. This standard does not provide procedures for the measurement of occupational noise exposures attributable to the rise of earphones or telephone receivers. This standard presents recommended practices for utilizing instrumentation such as a sound level meter, noise dosimeter, integrating sound level meter, and acoustical calibrators. Guidelines are provided for measurement conditions such as the acoustical environment, measurement activities, and operational variations. The parameters surrounding the noise and its impact on the selection of instrumentation is presented. Specific guidelines for using a sound level meter, a noise dosimeter, and an integrating sound level meter are presented. Guidelines for documentation and reporting of the measurement of occupational noise exposure are specified.
