Abstract

Reduction of noise in a car cabin due to road irregularities has been a subject of research for many years. For reducing such a noise, we propose the H2-based Active Structural Acoustic Control (ASAC) method that uses detailed acoustic models obtained by system identification, from the actuators and the shakers to the driver's ears sound pressure level. During experiments in a semi-anechoic room with a compact car, we verify the effectiveness of the proposed approach by obtaining overall noise reduction over the frequency range of 80∼400Hz at the driver's ears.
