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 (SRPn (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. |

1. 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 sources of interest, comprising the steps of:
obtaining, using an array of at least two microphones, environment audio signals corresponding to said one or more sources of interest and to the ambient noise emanating from said sound environment; calculating, using the environment audio signals, environment steered response powers (SRP (t, f, θ, φ) corresponding each to the power of said sound environment under particular reference conditions; obtaining, using said array of at least two microphones, noise audio signals corresponding to the ambient noise emanating from said sound environment under particular reference conditions; calculating, using said noise audio signals, noise steered response powers (SRPn (t, f, θ, φ) corresponding each to the power of said ambient noise for one orientation of the plurality of orientations; and estimating the direction of arrival of said sound source of interest by identifying, among said one or more orientations, a set of orientations using said source steered response power and said noise steered response power. |
