SAE J1075

Description / Abstract: This SAE Standard sets forth measurements 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.

Purpose

The purpose of this SAE document is to set forth procedures that may be used by construction site management for self regulation and construction site planning or by state and local officials for the enforcement of construction site noise regulations. Two measurement methods are provided to obtain the time-integrated equivalent sound level, leq, emitted by construction site activity. First, a sampling procedure is recommended for use with a sound level meter. Second, a measurement procedure using an integrating sound level meter is presented. The latter procedure is generally preferred. Use of this document provides sound level data representative of the complex time-varying sounds emitted by construction activities, which may be used to estimate community reaction to the construction activity.
