Speech intelligibility, spatial unmasking, and realism in reverberant spatial auditory displays
MetadataShow full item record
Many auditory displays strive to include accurate directional spatial cues, but few provide robust cues for source distance. This paper considers how including echoes and reverberation in a spatial auditory display (in order to create salient cues for source distance) impacts other aspects of performance, especially speech intelligibility and spatial unmasking. Preliminary results from masked speech intelligibility studies (together with results from previous experiments investigating sound localization) suggest that including modest amounts of reverberation (such as that present in a typical, everyday room) can provide useful distance information without causing large performance degradations on other tasks.
