Active suppression of acoustic resonance
Active suppression of acoustic resonance
The minimization of acoustic potential energy has been proposed as a method of actively controlling a harmonic reverberant sound field. In this paper an analysis of plane waves in a finite length duct provides insight into the physical mechanisms of this method and allows comparison with two other methods, the acoustical virtual earth and the absorbing termination. A practical technique of achieving the reduction of acoustic potential energy is presented and discussed.

Abstract
The minimization of acoustic potential energy has been proposed as a method of actively controlling a harmonic reverberant sound field. In this paper an analysis of plane waves in a finite length duct provides insight into the physical mechanisms of this method and allows comparison with two other methods, the acoustical virtual earth and the absorbing termination. A practical technique of achieving the reduction of acoustic potential energy is presented and discussed.
