Definition of a New Parameter for use in Active Structural Acoustic Control

Utah State University

A new parameter was recently developed by Jeffery M. Fisher (M.S.) for use in Active Structural Acoustic Control (ASAC) which showed potential for achieving better sound radiation reduction than current parameters. This parameter, known as “Vcomp,” was shown analytically to produce results comparable to control of radiated sound power and volume velocity on a simply supported plate. However, experimental tests were less encouraging. This paper is an overview of current efforts to better understand and improve the Vcomp parameter so that it may be used to effectively control sound radiation from simply supported and clamped structures.
