Abstract
This paper presents the results from a hardware demonstration of a noise ra diation sensor for a baffled rectangular plate. The sensor consists of an a rray of independent piezoelectric patches connected to a linear combiner. T he coefficients of the linear combiner are computed in order to reconstruct (in real time) the volume displacement (or velocity). The robustness of th e volume displacement sensor with respect to the location of the disturbanc e source is investigated. (C) 2001 Academic Press.
