摘要
This invention is in the operation of the vehicle , or automobile components in the operation of any of the components of the in the acoustic signal generated inside which is related to a method for identifying the scan Iquique noise . According to the present invention , the sound signal is detected , the amplitude spectrum at least showing the amplitude distribution in the frequency domain of the amplitude spectrum of the acoustic signal is generated at the two time , and the presence of a bus Iquique noise by evaluation of at least two of the amplitude spectrum whether it is identified .
