Measurement of Minimum Noise Emitted by Road Vehicles
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 acoustical 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
Rationale: This Surface Vehicle Standard provides a method to measure the minimum noise emission of road vehicles and external sound generation systems intended for the purpose to provide acoustic information to pedestrians. This standard provides a performance-based and technology neutral test procedure. This standard reflects the development of engine and propulsion technologies which have noise emission characteristics that cannot be correctly tested under existing SAE Standards.
