A method of superimposing spatial auditory cues on externally picked-up microphone signals

摘要

The present invention relates to a method of superimposing spatial auditory cues to an externally picked-up sound signal (s E (t)) in a hearing instrument (107, 109). The method comprises steps of a generating an external microphone signal (s E (t)) by an external microphone arrangement (105) and transmitting the external microphone signal (s E (t)) to a wireless receiver of a first hearing instrument (107) via a first wireless communication link (104). Further steps of the methodology comprise determining response characteristics of a first spatial synthesis filter (g L (t)) by correlating the external microphone signal (s E (t)) and a first hearing aid microphone signal (s L (t)) of the first hearing instrument (107) and filtering the external microphone signal (s E (t)) by the first spatial synthesis filter (g L (t)) to produce a first synthesized microphone signal (y L (t)) comprising first spatial auditory cues.
