Measurement of noise emitted by accelerating road vehicles. Engineering method - M and N categories Ingestion-build-48068 1) Top hung (open out)BS ISO 362 1: 2007 specifies an engineering method for measuring the noise emitted by road vehicles of categories M and N under typical urban traffic conditions. The specifications are intended to reproduce the level of noise generated by the principal noise sources during normal driving 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
