Sensitivity Analysis of the Noise Response in Cab Lined With Sound Absorbing Materials on the Panel

It is one of the major methods to reduce the interior noise of the cab with sound absorbing materials on the panel. In this paper, the sensitivity of the noise response in cab lined with sound absorbing materials on the panel was calculated according to the complex mode theory and sensitivity analysis method. The analysis results indicated that the sound absorbing materials on the roof of the cab have the largest sensitivity to the interior noise at the driver's ear position.
