Abstract
A method operates a hearing device where a first directional signal and a second directional signal are generated in the hearing device from a sound signal of the environment. A parameter is determined based on the first directional signal and the second directional signal, which represents a quantitative measure of the stationarity of a sound signal. A noise-optimized signal is generated from the first directional signal and the second directional signal based on the parameter. The method is performed by a hearing device having a first microphone and a second microphone for generating a first directional signal and a second directional signal. The hearing device is configured to implement the corresponding method.
Claims11
A method of operating a hearing device, which comprises the steps of:
- generating a first directional signal and a second directional signal in the hearing device from a sound signal obtained from an environment;
- determining a parameter based on the first directional signal and the second directional signal, the parameter representing a quantitative measure of a stationarity of the sound signal;
- generating a noise-optimized signal from the first directional signal and the second directional signal based on the parameter;
- and
- determining the parameter from the noise-optimized signal in a signal feedback loop.
A hearing device, comprising:
- a first microphone for generating a first directional signal;
- a second microphone for generating a second directional signal;
- a processor programmed to:
- determine a parameter based on the first directional signal and the second directional signal, the parameter representing a quantitative measure of a stationarity of a sound signal;
- generate a noise-optimized signal from the first directional signal and the second directional signal based on the parameter;
- and
- determine the parameter from the noise-optimized signal in a signal feedback loop.
