Abstract
In the instant of start-up, idle or stop, sounds that with high frequency and particularly harsh, will be heard by the passengers inside the car. According to the mechanism of noise, it can be divided into three categories: electromagnetic noise, mechanical noise and aerodynamic noise. This paper creates a noise test system based on LabVIEW, for more in-depth analysis of the noise. Through the analysis of the test data, error of this system is less than 1%, in line with the general design requirements. In addition, it has a superior function than the traditional sound level meter. Specific functions are as follows: (a) cheaper; (b) display of noise waveform; (c) data preservation; (d) capture amplitudes beyond the rated point; (e) frequency spectrum analysis
