✦ Synopsis

Inclusion of non-resonant component is expected to improve the estimation of response of a structure to acoustic excitation. In this paper this is veri"ed experimentally. A typical plate is subjected to acoustic excitation in a reverberant chamber and the acceleration responses are measured. The experimental results match well with the theoretical estimates that are made incorporating the non-resonant component. The results show that if the non-resonant part is not considered, the estimated response is in large error. This is seen in the spatial average response as well as in the response levels for a con"dence coe$cient of 99%.
