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
What this study is about
In the sponsor’s own words, from the registry.
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.
