Method for dereverberation of an acoustic signal and system thereof

摘要

A method for estimating a reverberation signal component of an acoustic signal detected by a microphone (12), the acoustic signal comprising a direct sound component (13) and the reverberation signal component (14), the method comprising the following steps:
- detecting the acoustic signal,
- estimating the reverberation signal component (14), wherein the estimating step comprises the step of
- calculating an incorrect reverberation signal component R under the assumption that the reverberation signal component (14) has a predetermined relationship to the direct sound component (13), and
- minimizing the error resulting from the assumption that the reverberation signal component (14) has a predetermined relationship to the direct sound component (13) so as to estimate the reverberation signal component (14).
