Binaural hearing aid system for compensation of microphone deviations based on the wearer's own voice

摘要

A hearing aid system is enabled for binaural microphone adjustment by way of the wearer's own voice. The hearing aid system has a first and a second hearing aid having a first and a second acousto-electric converter. The converters have a signal link with a signal processing unit which determines and compensates for signal deviations caused by the first and second acousto-electric converters on the basis of signals from the wearer's own voice. The wearer's own voice is recognized by a special facility.

主权项

1. A hearing aid system to be worn by a hearing aid wearer, the hearing aid system comprising:
a first hearing aid and a second hearing aid, said first hearing aid having a first acousto-electric converter configured to convert an incoming acoustic signal into a first electrical signal, and said second hearing aid having a second acousto-electric converter configured to convert a second incoming acoustic signal into a second electrical signal; a signal processing unit connected, by way of a signal link, with said first and second acousto-electric converters; said signal processing unit being configured to determine and to compensate for signal deviations between the first and second electrical signals on the basis of the first and second electrical signals from the wearer's own voice, wherein the wearer's own voice is characterized by a symmetry of the first and second audio signals at the first and second acoustoelectric converters; a facility configured for recognizing the wearer's own voice, said facility having a signal link with said first and the second acousto-electric converters and being configured to signal to said signal processing unit a recognition of a signal from the wearer's own voice.
