| 抄録: | It is well known that detectability of signals could be improved by using directional information. This phenomenon is referred as to spatial release from masking (SRM). Interaural time difference (ITD) and interaural level difference (ILD) are used as significant spatial cues in SRM. However, the phenomenon in which ILD yields the great SRM has not yet been considered to construct models for SRM. This paper proposes a binaural hearing model that accounts for the SRM using the ITD and ILD cues. Firstly, our model divides target signals and maskers incoming two ears using a gammatone filter bank as auditory filter. Next, we consider to implement ITD and ILD processes independently and in parallel. Finally, we connect the outputs of two processes for the final masking release occurred by ITD and ILD. The results of the modelshow the same tendency observed as the empirical data. Consequently, our binaural hearing model can simulate the SRM. |
