声学 机动车辆定置噪声声压级测量方法
Application Summary AI generated
This standard specifies the test methods for measuring the sound pressure level of stationary road vehicles, including engine and exhaust noise, under controlled conditions. It is applied by vehicle manufacturers and inspection authorities in China to verify compliance with national noise emission limits for type approval and production conformity testing. The standard is relevant for all motor vehicles, such as cars, trucks, and buses, during stationary operation in a semi-anechoic or open-field test environment.
