Abstract
This paper suggests an active sound control system using vibration actuators and microphones, called an active Vibro-acoustic enhancement (AVAE), to obtain a desired engine sound in a vehicle while the vehicle is running up. In this system, the actuator is located on a body panel suitable for transmitting a sufficient level of sound to an interior room. Exciting a thin body panel is advantageous in producing a low frequency sound, but makes it difficult to secure control performance and stability due to the long impulse response function. To overcome this drawback, several methods are adopted for AVAE in addition to the conventional FxLMS algorithm and each effect is compared together in simple noise reduction cases. Finally, this AVAE system is demonstrated through the driving test of a vehicle. From the results, this system is expected to become an alternative way to the active noise control system using acoustic speakers for noise cancellation or target sound tracking in a vehicle.
