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

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.
