자동차 실내 엔진 소음의 능동제어에 관한 연구

With the advance of the starrlard of living, the demand on automobile reqires beyond the traffic device, therefore the interior noise has been the important factor for improvement of ride quality. The frequency components in the vehicle cabin on driving are effeted by the frequency of running engine. Specially, in low frequency ranges(20-200Hz), rooming noise of structual coupling noise is generated by the coupling of vibration of driving system and acoustical mode of interior. In this study, multichannel adaptive algorithm was realized and the noise of specific region in the interior of automobile was intended to be reduced through the control of engine noise in the vehicle cabine using developed algorithm.
