Abstract
This paper presents an aciWe wave control method of a three dimensional rectangular enclosure and to clarify fundamental properties of the control system. Firstly, a transfer matrix method for the target system is newly introduced to describe the wave dynamics in the enclosure. This is followed by the derivation of feedforward control laws for absorbing reflected waves or eliminating transmitted waves. Then, from a viewpoint of numerical analyses, basic properties of the proposed method is verified. It is found that the transmitted wave eliminating control enables the generation of silent zone, and the reflected wave absorbing control enables the inactivation of acoustical modes in the controlled direction.
