This paper describes an approach for the reduction of structure-bome noise in vehicle cabine. First, we developed the method of calculating structure grid participation factor using MSC/NASTRAN. And then it was used to prediet structure-bone noise in vehicle cabine. Finally, interior noise levels around passenger's ear position are predicted and reduced by structural modification based on structure grid participation factor analysis.
