摘    要:利用互易性原理,提出了一种空气声传播路径实验方法.首先测得各声源对于车内噪声的传递函数,进而得到各声源对于车内噪声的贡献度.根据声源识别结果,对汽车车身进行吸声、隔声设计,结果表明,车内地板隔声量从前向后分别提高了1.83~9.74 dB(A),汽车车内噪声下降了4.7 dB(A).

关 键 词:汽车  声源识别  传递函数  噪声控制

Abstract:Based on the principle of reciprocity,an experimental method was developed for the air-borne propagation path,and by doing so,the transfer functions were established from the sound sources to vehicle interior noise,and then the contributions from the different sources were got.According to the result of the noise sources identification,car body was redesigned by using techniques of the sound absorption and sound insulation.Case research showed that acoustical reduction factor of the vehicle floor increased ...
Keywords:Vehicle  Noise source identification  Transfer function  Noise control
