Hearing apparatus
First Claim
1. A system comprising:
- a hearing apparatus includingat least one first microphone and a second microphone that generate a first microphone signal and a second microphone signal respectively, the at least one first microphone and the second microphone being arranged in a first hearing device and a second hearing device; and
an external device including a third microphone that generates a third microphone signal, and a signal processing unit;
wherein, in the signal processing unit, the third microphone signal and at least one of the first microphone signal or the second microphone signal are processed together thereby producing an output signal with an enhanced signal to noise ratio compared to the first microphone signal or the second microphone signal,wherein the signal processing unit comprises an adaptive noise canceller unit into which the third microphone signal and the at least one of the first microphone signal or the second microphone signal are fed and further combined to obtain the output signal, andwherein the adaptive noise canceller unit further comprises a comparing device in which the first microphone signal and the second microphone signal are compared for target speech detection, the comparing device generating a control signal for controlling the adaptive noise canceller unit such that the adaptive noise canceller unit is adapting only during an absence of target speech activity.
