Abstract
A method for localizing one or more sound sources of interest placed within a sound environment comprising ambient noise by estimating the directions of arrival (θ,φ) of said one or more sound source of interest comprising the steps of: calculating the environment steered response power (SRP (t, f, θ, φ)) corresponding to the steered response power of said one or more source of interest for one or more orientations using said environment audio signals; obtaining, using said array of at least two microphones, noise audio signals corresponding to the audio signals emanating from said sound environment under particular reference conditions; calculating a noise steered response power (SRP(t, f, θ, φ)) corresponding to the steered response power of the ambient noise for said one or more orientations using said noise audio signals; and estimating the direction of arrival of said sound source of interest.
