A study on ANC system to reduce the noise level inside a half-scaled-compartment-cavity-model was carried out. Numerical analyses were performed to find the acoustic resonance modes of the cavity model and to select the proper locations of the control sources inside the cavity having the noise sources. The amplitudes and the phases of control sources at fixed positions were calculated for the ANC system to reduce the acoustic potential energy of some specific points inside the cavity.The results of the experiments using the half-scaled-compartment-model to verify those of the numerical simulation were shown. These results showed the possibility to develop ANC system making use of the current loudspeakers in car audio system without any change of layout and additional control speakers.
