A Study on Effects of Sound Masking on Speech Intelligibility

Abstract

This study relates to the effects of sound masking on speech intelligibility. The International Standards such as ANSI SII and ITU-T PESQ were used for the evaluation on the speech intelligibility under masking noise environments. Also, for the subjective evaluation, the listening test was performed by people. Experimental results on speech intelligibility proved that sound masking method is effective for masking the unwanted speech signals of other people.
