In automotive industry, weight reduction has been one of the most effective techniques in design of more fuel-efficient vehicles. However, reducing the body weight of the vehicle would unavoidably increase the noise level and vibration inside the automobiles. The engine noise, road noise, exhaust noise, and aerodynamic noise are the most important sources of noise that contribute to a vehicle's overall interior noise. To date, the focus of most studies has been reduction of low frequency noise and vibration originated from the engine and the road. Such noise, are difficult to attenuate by means of passive methods such as energy absorption. Literature shows that active control systems instead, have proven to be the most effective solutions yet and a promising method, in comparison to the conventional passive techniques, for reducing the low frequency interior noise level and vibration inside enclosures. This technique, therefore, is expected to offer an acceptable level of comfort inside the drivers' cabin without the need for additional weight. To examine this, adaptive filtering techniques have been applied to non-stationary signals in an enclosure in an attempt to achieve non-destructive active noise control inside in a similar body such as automobiles. The results are presented, analysed and discussed.
