Physical Aspects in Active Noise and Vibration Control

摘要

Active Noise and Vibration Control (ANVC) means generation of intentional sound and/or vibration fields in order to change those caused by existing sources. It has applications in the industry, including the car and aircraft industries, structural design and audio engineering among others. Active noise and vibration control involves several disciplines that link mechanics with HiTech. It necessitates knowledge of physical and theoretical acoustics, electro acoustics, control engineering and electrical engineering.
