Abstract
At least one acoustic parameter of an environment is obtained by emitting a sound signal emitted, receiving a sound signal received, estimating a sampling frequency shift and of a temporal shift between the emission and reception devices on the basis of impulse responses obtained on the basis of portions of the sound signal received and of corresponding portions of the sound signal emitted, obtaining a corrected sound signal received by applying to the sound signal received a sampling frequency shift correction and a temporal shift correction on the basis of the estimating, determining the impulse response of the environment on the basis of portions of the corrected sound signal received and of corresponding portions of the sound signal emitted, and obtaining acoustic parameters of the environment on the basis of the impulse response.
