Automotive consumers are always looking for improvements in comfort, safety, fuel economy and cost. Engineers are addressing the cost and fuel economy issues with lighter weight chassis and high performance engines. These new designs, however, have a negative impact on the NVH comfort (Noise-Vibration-Harshness) of the vehicle. Significant research and development has been done on using active sound and vibration control technology in passenger vehicles. Automotive platform designs are now incorporating DSP hardware (Digital Signal Processing) to control various systems, including the car audio system. With DSP available in the vehicle and with the dramatically decreasing cost of DSP hardware, active control technology has become a cost-effective solution to cabin NVH issues. This paper provides a brief description of active control technology and discusses applications of this technology in the automotive industry. Next, it describes how 'seamless' and cost effective the integration of active control can be into systems that already exist or will exist in vehicles. Lastly, the successful results of an active control system in an automobile are presented.
