Subjective Evaluation of a Sound Processing Method for Hearing Aids on Auditory Distance Perception

Not Applicable

Completed

• Conditions: Hearing Disorders; Hearing Loss, Sensorineural

• Registration Number: NCT03512951
• Lead Sponsor: Sonova AG

Brief Summary

Within the course of this study, a signal processing feature has been developed at Ecole Polytechnique Fédérale de Lausanne (EPFL), in collaboration with Sonova AG, in order to enhance the listening experience with remote microphone systems. In particular, the developed feature is supposed to improve the so-called audio-visual fusion, i.e. the fact to perceive the sound as coming from the physical location of the source. One of the main goals of the present study is to evaluate the extent to which this feature reaches that objective.

Primary Outcome Measures

Name	Time	Method
Auditory distance estimation	6 months (study completion)	This objective is assessed by using a single outcome, which is the perceived auditory distance, as reported by the patient on a graphical user interface. The auditory distance is measured using an arbitrary scale (between 1 and 5) as available with sliders on a graphical user interface (GUI).
