Abstract: Supercharger noise will greatly reduce the acoustic quality of the vehicle, causing noise interference to drivers and passengers. This paper first describes the structure, principle and characteristics of the supercharger, analyzes the generation mechanism of various types of noise, and finds out the enhancement method, and then judges the effectiveness of the enhancement method by combining the noise comparison test before and after the enhancement with the subjective evaluation of personnel. Finally, we find out the relevant suggestions of various noise enhancement methods, and effectively apply them in the specific development products, and achieve good results.

Key words: Supercharger noise; Acoustic quality; NVH performance; Subjective evaluation
