This SAE Standard sets forth measurement procedures and instrumentation to be used for determining a “representative” sound level during a representative time period at selected measurement locations on a construction site boundary. The document is not intended for use in determining occupational hearing damage risk. Determination of a representative time period is left to the judgment of the user.

The requirements for setting up and operating the machinery, the microphone array and the size of the hemispherical measurement surface are given in this recommended practice. This recommended practice shall be used in conjunction with ISO 4872-1978, which gives the basic criteria for the acoustic environment, instrumentation, microphone positions, procedures for the measurement of the A-weighted sound pressure levels and the calculation of the A-weighted sound power levels.
