Abstract
Interior noises in tractor cab are composed of direct sound and reverberation sound.The reverberation sound which has a great contribution on the noise is concerned with the lining of cab wall.In this paper the noise level has been calculated after the sound was absorbed by tractor cab wall.The results were verified by experiment.The interior noise is reduced 2.3~3.1dB(A)after sound-absorbing lining.
