HISTORICAL
J2889/1_201205
This SAE Standard is derived from SAE J2805 and specifies an engineering method for measuring the minimum noise emitted by road vehicles. The specifications reproduce the level of noise which is generated by the principal vehicle noise sources consistent with minimal noise emission in urban traffic. The method is designed to meet the requirements of simplicity as far as they are consistent with reproducibility of results under the operating conditions of the vehicle. The test method requires an acoustic environment which is only obtained in an extensive open space. Such conditions usually exist during: Measurements of vehicles for regulatory certification Measurements at the manufacturing stage Measurements at official testing stations The results obtained by this method give an objective measure of the noise emitted under the specified conditions of test.
