In the first part of this paper, an analysis of the cab noise of an agricultural tractor was presented. In this study, using the results of the previous analysis, 2 passive noise control measures (sound insulation and absorption) were incorporated to reduce the noise level inside the cab. These measures of noise control reduced the total noise level by 6.2 dB at the operator position inside the cab.
