ResumenAn active sound control (ANC) system has been developed to reduce the booming of a van arisen when the engine noise excites some modes of the passenger compartment. Specially the SO-250 HZ frequency range is of primary interest. The intention is to implement a feedforward system, using microphones as error sensors and loudspeakers as secondary sources. First, a reference signal, coherent with the unwanted noise, has to be searched. The acoustic field inside the van is expressed as the sum of a series of acoustics modes. The optimal locations of loudspeakers are found by simulated annealing. Finally, the multichannel active noise control system is implemented using a commercial system. Measurements of noise reduction has been carried out in the semianechoic room at NECT-E under usual driving conditions (3rd gear, fast acceleration).
