Abstract
In this paper, analytical and experimental investigations conducted into the design and use of fiber-tip based Fabry-Perot sensors for control of structural acoustics are presented. Noise is transmitted into the enclosure through a flexible boundary, and the fiber-tip sensors are designed for acoustic pressure and air particle velocity measurements inside and outside the enclosure as well as panel acceleration measurements. The benefits of these sensors for realizing zero spillover control schemes and other schemes are discussed.
