Abstract

Abstract: There were some drawbacks in the measurement of acoustic sensitivity by vector synthesis method for vehicle's interior noise; that is, the results of measurement are influenced easily by excitation forces, the method is carried out using the multi-point excitation. It is verified that this method, which can reduce the errors caused by nonlinearities and data processing, is better than old one to measure the acoustic sensitivity accurately in practice.

Key words: Acoustic sensitivity, Multi-point excitation, Noise
