Automotive Vehicles-Noise Emitted by Stationary Vehicles-Method of Measurement

This standard outlines procedures for measuring noise emitted by stationary vehicles. It provides guidelines on the setup, equipment, and methodology required to conduct noise tests under controlled conditions. The document specifies the positions and distances for sound level measurements, as well as the conditions under which the tests should be performed. It also includes details on calibration of measurement instruments and the processing of data to ensure consistency and accuracy. The standard aims to establish a uniform approach for noise assessment, facilitating comparisons between different vehicles and ensuring compliance with relevant regulatory requirements.
