Paper Abstract

This paper presents a new volume velocity sensor and its application in active structural acoustic control system. Utilizing the charge output equation of the PVDF piezoelectric film and orthogonal property of trigonometric function, a design strategy for a PVDF sensor detecting the volume velocity induced by a vibrating 2D structure is presented. The designed sensor is made of shaped strips of PVDF film. The experimental implementation of the new sensor in an active structural acoustic control system is then presented. The experimental results obtained validate this new type of volume velocity sensor, and significant attenuation of the radiated sound field is obtained.
