Abstract
Processing two input signals in a hearing aid with a first source separation and a second source separation is provided. A comparison of a first correlation with a second correlation and with a change in the first coefficient set as a function of a second coefficient set when the second correlation is smaller than the first correlation, with the second coefficient set being changed as a function of the first coefficient set when the second source separation is reset.

A method for processing at least two input signals in a hearing aid, with the input signals being dependent on an acoustic signal, the method comprising:
- processing a plurality of input signals via a first source separation:
- continuously determining a first correlation of a plurality of first output signals from the plurality of input signals and a first correlation coefficient set, and
- continuously determining the first coefficient set as a function of the first correlation;
- processing the plurality of input signals via a second source separation:
- continuously determining a second correlation of a plurality of second output signals from the plurality of input signals and a second coefficient set, and
- continuously determining the second coefficient set as a function of the second correlation;
- comparing the first correlation with the second correlation;
- changing the first coefficient set as a function of the second coefficient set when the second correlation is smaller than the first correlation;
- and
- changing the second coefficient set as a function of the first coefficient set when the second source separation is reset.
An apparatus for processing two input signals which are dependent on an acoustic signal in a hearing aid, with the apparatus comprising:
- a processing unit that continuously determines two first output signals and a first correlation of the two first output signals from the two input signals with a first coefficient set and continuously determines the first coefficient set as a function of the first correlation and continuously determines two second output signals and a second correlation of the two second output signals from the two input signals with a second coefficient set and continuously determines the second coefficient set as a function of the second correlation, with the processing unit changing the first coefficient set as a function of the second coefficient set, when the second correlation is smaller than the first correlation, with the processing unit resetting the second coefficient set as a function of the first coefficient set.
