Abstract

Customers often complain a vehicle noise although the interior noise A-weighted sound pressure level has reached the same level of excellent vehicle. To solve the problem of large interior noise and messy sound of an own brand SUV, relative approach analysis is utilized, which is detected the frequency component perceived by human hearing easily. Then, used the method of separating the noise source, confirming and rectifying the noise source. Optimized test data show: A-weighted sound pressure level of the SUV interior noise in neutral idle condition was reduced from 43.86dB(A) to 37.5dB(A), reached the same level of joint-venture brand SUV outstanding level. Clutter sound disappeared, sound quality subjective evaluation value improved. Relative approach analytical method is sensitive to human hearing detected frequency band, therefore, using this method can quickly and accurately lock the noise source, effective solved the problem of mismatch between listening experience and sound pressure level.
