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.

Conditions

• Hearing Disorders
• Hearing Loss, Sensorineural

Interventions

Type	Name	Description
OTHER	Digital signal processing algorithms	The intervention consists in applying five processing on some recorded speech signals. In particular, the processing performed by one specific algorithm is compared against the four other. The applied processing is supposed to restore sound externalization (expected audio-visual fusion).
