Abstract

A method for creating a model of reflective surfaces in a listening environment that may be applied to noise cancellation for a network of AVB/TSN loudspeaker components. A coordinator determines co-planarity and estimates orientation of all echoes of a stimulus by using recorded precise times of arrival, determined angles of arrival and the known, or estimated, locations of each loudspeaker component. The coordinator groups reflection points into planar regions based on co-planarity and estimated orientations to determine a location of each reflective surface in the listening environment thereby creating a model of all of the reflective surfaces in the listening environment.
