1. A method for detecting and localizing an acoustic source (2 or 12) in a one-dimensional or bidimensional industrial structure (1, 9), the acoustic source being a pinpoint source or of small extent, accidental of fortuituous in origin and emitting a wave which admits in the structure at least two wave modes, said wave being emitted and said two modes being propagated at different speeds, characterized in that the localization of the acoustic source is achieved by mode distinction through the evaluation of the detection time difference (262) between said two distinct modes. |
