To determine the main source and frequency distribution of the pneumatic noise of the supercharger compressor, the sound field characteristics of the compressor were studied using the broadband noise model and acoustic analogy method. The simulation results showed that the impeller was the main source of compressor aerodynamic noise, and the maximum compressor noise was generated at the impeller trailing edge. The impeller noise mainly occurred in the mid-frequency band. With the increase of harmonic frequency, the compressor sound power gradually decreased, and the sound power level reached the maximum at the first-order blade frequency. The aerodynamic noise of the compressor had obvious directivity at the nozzle of the compressor at the frequency of blade passage.
