Effects of Binaural Spatialization in Wireless Microphone Systems for Hearing Aids on Normal-Hearing and Hearing-Impaired Listeners.
Summary
This study investigates the possible benefits of using binaural spatialization techniques in digital wireless microphone systems for hearing aids. Speech intelligibility tests, speaker localization tests and preference tests are performed. The results of a diotic (current rendering) and a binaural (suggested rendering) rendering are compared.
