해석적 방법에 의한 부우밍 소음 저감 기술에 대한 연구

 This paper describes the analytical process to reduce booming noise level which affects the quality of passenger car. To obtain a reliable structural model, each stage of model such as body in white, trimmed body, total vehicle model was validated with test results. And the acoustic pressure sensitivity was calculated by structure-acoustic coupled analysis and was compared to test results at driver's ear. Frequency range up to 150 Hz was focused on.
