Abstract

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.

Description

technical field [0001] The present disclosure relates in a first aspect to a method of superimposing spatial auditory cues to an externally picked-up sound signal in a hearing instrument. The method comprises the steps of generating an external microphone signal by an external microphone arrangement and sending the external microphone signal via a first wireless communication link to a wireless receiver of the first hearing instrument. Further steps of the method include determining a response characteristic of the first spatial synthesis filter by correlating the external microphone signal with the first hearing aid microphone signal of the first hearing instrument; and filtering the external microphone signal by the first spatial synthesis filter , to generate a first synthesized microphone signal comprising a first spatial auditory cue. Background technique [0002] A hearing instrument or hearing aid typically comprises a microphone arrangement comprising one or more mi...
