摘要
Abstract
Low-frequency components of braking noise usually dominate the internal noise for some kinds of automobiles. Since the low-frequency noise has high energy, the strong interior noise will reduce the comfort for the passengers. In this paper, the braking noises at the driver’s ears in three different cars travelling at 60km/h in emergency braking were collected and analyzed in time-frequency domain. Results of analysis agreed well with the real ride-perception in a testing car. Then, the active braking noise control simulation using adaptive LMS algorithm was implemented. The results show that the low-frequency noise, especially in the range of 20 Hz-50 Hz, is greatly eliminated.关键词
