Abstract

A least-squares approach for designing ?lters can provide an effective way of controlling sound pressure in speci?c sound zones. This paper compares two least-squares approaches (with two and four controlling loudspeakers) against the plane wave cancellation method, speci?cally chosen due its effectiveness in rectangular room conditions. The methods are ?rst compared in an ideal rectangular room scenario and then tested outside of an ideal set-up to check which method performs best. Findings suggest that the a least-squares approaches consistently outperforms the plane wave cancellation method under all tested situations.
