Evaluation of a Binaural Spatialization Method for Hearing Aids, in Terms of Speech Intelligibility, Speaker Localization and Subjective Preference.
In Brief
A Phase 3 clinical trial evaluating Hearing Aids for Sensorineural Hearing Loss. Completed, enrolled 40 participants across 1 site.
Detailed 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.

Interventions
The only intervention consists in applying a specific processing on some recorded speech signals, and comparing the performance obtained with such processed samples with ones that have not been processed. The applied processing is a binaural spatialization method that consists in filtering an original audio signal to get a left and right versions (for the two ears). The binaural rendering gives the impression that the speech signal (and thus the speaker) is located in a desired position in the environment.
