This study presents the feedback control of flexural waves propagating in a rectangular panel. The objective of this paper (part 2) is to experimentally implement the feedback wave control method which was proposed in part 1 of the two series pape...

The experimental validation of a generalised approach to the sensing of orthogonal contributors to the global error (acoustic potential energy) within a coupled structural-acoustic cavity is presented. The goal is the measurement and control of th...

This paper deals with the eigenvalue problem of a coupled rectangular cavity comprising five rigid walls and one flexible panel frequently employed in much literature. It is the purpose of this paper to derive explicitly the eigenpairs of the coup...
This paper presents global noise reduction in an enclosed sound field using feedback control based on the affinity between cluster control and suppression of acoustical energy density. First, an enclosed sound field is expressed in terms of a stat...
