Abstract:
A system and method for estimating the direction of arrival of sounds. One method including the steps of: forming a reference signal; detecting sound with two or more spatially separated, directional or spatially separated directional, microphones to produce two or more output signals; calculating the relationships between each of the two or more output signals and the reference signal; and estimating the direction of arrival based on differences between the relationships.
