Ages 18 to 80 · All sexes · Healthy volunteers welcome
Full eligibility criteria
Inclusion Criteria: Normal-Hearing Subjects * 18 to 35 years of age * Audiometric thresholds that do not exceed 20 dB HL at any frequency from 250 to 8000 Hz * Able to provide informed consent and understand experimental instructions * Normal or corrected-to-normal vision Inclusion Criteria: Hearing-Impaired Subjects * 18 to 80 years of age * Documented sensorineural hearing loss * Able to provide informed consent and understand experimental instructions * Normal or corrected-to-normal vision Exclusion Criteria (some experiments) * Non-native speakers of English
About the study
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.
