Abstract (en)
[origin: WO2017089688A1] The invention relates to a method for estimating sound reverberation in a medium (7), which comprises the following steps: (a) a measurement step in which an acoustic signal emitted in the medium is collected; (b) a step of determining the distribution of the acoustic energy decrease rate, during which a distribution of the acoustic energy decrease rate is determined from the acoustic signal collected in step (a); and (c) an estimation step during which a reverberation time and a level of reverberation of the sound in the medium is estimated by regression from a characteristic function of the distribution of the acoustic energy decrease rate determined in step (b).
