Abstract
A data-processing method for determining at least one spatial coordinate of a sound source emitting a sound signal, in a three-dimensional space, includes the following steps: obtaining at least one first signal and one second signal from the sound signal, collected according to separate directivities by a first sensor and a second sensor; deducing from the first and second signals an expression of at least one first spatial coordinate of the sound source, the expression comprising an uncertainty; determining additional information relating to the first spatial coordinate of the sound source, from a comparison between the respective features of the signals collected by the first and second sensors; and determining the first spatial coordinate of the sound source on the basis of the expression and the additional information.
