How to superimpose a spatial auditory cue on top of an externally picked-up microphone signal

摘要

The invention on one hand relates to a method of superimposing spatial auditory cues on externally picked-up microphone signals in a hearing instrument. The method comprises the following steps: an external microphone apparatus generating an external microphone signal and transmitting the external microphone signal to a wireless receiver of a first hearing instrument through a first wireless communication link. The method further includes the following steps: associating the external microphone signal and a first hearing auxiliary microphone signal of the first hearing instrument so as to determine a responding characteristic of a first spatial synthesis filter; and filtering the external microphone signal by the first spatial synthesis filter so as to generate a first synthesis microphone signal including a first spatial hearing cue.
