Improving Spatial Perception and Speech Understanding in Multitalker Mixtures (NCT05260307)
🩺 Plain-English Summary (8th-Grade Level)
The purpose of this study is to investigate several approaches for improving spatial perception and speech intelligibility in multitalker listening situations for hearing-aid users. The hypotheses are that spatial perception and speech intelligibility will be improved by (1) increased high-frequency audibility, (2) speech envelope enhancement, and/or (3) appropriate sound image externalization.
