摘要
本文提出了一种利用车辆行驶时产生的声音信号进行汽车噪声源识别的新方法。对所采集的车辆行驶时的声音信号,运用小波变换对信号进行处理,找出汽车噪声主要集中的频段,通过与汽车各噪声源位于的频段进行比较就可以较为准确地找出汽车的主要噪声源,并通过实验论证了上述方法的可行性。
In this paper,a new method of identification technique of vehicle noise sources with vehicle noise signal is presented.The vehicle noise is processed with wavelet transform,and the frequency band that noise concentrate mainly is found out.The main noise source of vehicle can be found.At last,the result of the experiment proves this method is feasible.
