Book excerpt: This SAE Recommended Practice is equivalent to ISO Standard 3621981 except for the differences detailed in the Appendix, and includes the modifications adopted by WP29 in ECE R51.This SAE Recommended Practice specifies an engineering method for measuring the noise emitted by accelerating highway vehicles of all types (except motorcycles) in intermediate gears with full utilization of the available engine power.The method is designed to meet the requirements of simplicity and reproducibility of results under realistic vehicle operating conditions.Measurements relate to operating conditions of the vehicle which give the highest noise level consistent with urban driving and which lead to reproducible noise emissions. Therefore, an acceleration test at full throttle from a stated engine or vehicle speed is specified.The test method calls for an acoustical environment which can only be obtained in an extensive open space.If measurements have to be carried out on the road in an acoustical environment which does not fulfill the requirements stated in this SAE Recommended Practice, it should be recognized that the results obtained may deviate appreciably from the results obtained using the specified conditions.The results obtained by this method give an objective measure of the noise emitted under the prescribed conditions of test. However, it is necessary to consider the fact that the subjective appraisal of the annoyance of different classes of motor vehicles is not simply related to the indications of a sound level meter.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Standard is equivalent to ISO 362-1:2015 and specifies an engineering method for measuring the noise emitted by road vehicles of categories M and N under typical urban traffic conditions. It excludes vehicles of category L1, L2, L3, L4, and L5.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 conditions of the vehicle.The test method requires an acoustical environment that is obtained only in an extensive open space. Such conditions are usually provided for during: Measurements of vehicles for regulatory certification and/or type approval. Measurements at the manufacturing stage. Measurements at official testing stations. SAE J2805 is the technical mirror of ISO 362-1. SAE J2805 and ISO 362-1 serve to measure in a performance-based and technology-neutral manner the 90% percentile exterior sound emission of road vehicles. The test procedure is based on extensive statistical investigations of vehicle operation in real traffic and is therefore well correlated to actual in-use sound emissions.The 2020 revision of SAE J2805 incorporates updates reflecting practical experience and clarifications to improve the understanding of users regarding the intent of the standard.
