Abstract

Physical and biological aspects in active sound and vibration control G. Rosenhouse Faculty of Civil Engineering-Technion, Haifa, Israel Abstract Sound is a physical phenomenon that involves mechanical waves. It exists in nature and can also be generated by man made devices. Generation of intentional sound andlor vibration fields in order to change existing sound and vibration fields is Active Sound and Vibration Control (ASVC). Active Noise and Vibration Control (ANVC) is a part of ASVC, and it means attenuation of undesired sound and noise. ANVC embraces reduction of noise and vibration in many applications, as these in the car and aircraft industries, structures and audio engineering among others. On the other hand, ASVC has many disciplines other than noise reduction, where mechanical waves couple with others or with different lunds of waves (electrical, optical, magnetic etc.) or with chemical processes. ASVC generation involves not only Hi-Tech technologies, but can be generated by other
