汽车定置噪声限值及测量方法研究

Investigation on Vehicle Noise Emitted by Stationary Road Vehicles and the Measurement Method

基于目前执行的定置噪声标准GB/T 14365-2017《声学机动车辆定置噪声声压级测量方法》,以某企业为例,重点分析了试验实施的具体方法,通过对标准内容解读,提出了一种同一车系定置噪声的视同判定方法,对整车企业具有一定的指导意义。

Based on the current standard of noise emitted by stationary road vehicles GB/T 14365-2017 Acoustics-Measure-ments of sound pressure level emitted by stationary road vehicles.This paper analysed the specific method of test imple-mentation according to an instance from an automotive enterprise.Through the interpretation of the standard content,a method to determine the same noise judgment condition for the same series vehicles has been introduced,which has a certain guiding significance for vehicle enterprises.
