Improving Spatial Perception and Speech Understanding in Multitalker Mixtures

Sex: All

Ages: 18 Years – 80 Years

Healthy volunteers: Yes

Phase: NA

Enrollment: 220

Sponsor: Boston University Charles River Campus

Summary

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.
