概要 Dereverberation processing is necessary for hearing-aid systems with a limitation of computational cost because reverberation degrades speech intelligibility in some reverberation environments. The spectral subtraction (SS) method is a simple and well-known technique as not only a noise-reduction method but also a dereverberation method. In dereverberation methods that are based on SS for hearing aids, it is desirable to estimate the reverberation power with blind processing. The SS-based blind-estimation method was proposed by Sunohara et al. using exponential averaging with attack and release time constants for single-channel speech signals.
