Oversized-pinna cue simulation barely improves vertical localization for hearing-impaired listeners
Evidence
The normal-hearing test subjects showed similar discrimination performance with the T, W, and N-type simulated pinna cues, as expected. However, the results for the hearing-impaired test subjects showed only marginally lower MAAs with the W and T-cues compared to the N-cues, while the overall discrimination thresholds were much higher for the hearing-impaired compared to the normal-hearing test subjects. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3048
