Patent ID: 8515107

Claim:
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, wherein the first output signals comprise different, non-autocorrelated output signals wherein the first correlation is minimized and the first output signals are maximally separated, 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, wherein the second output signals comprise different, non-autocorrelated output signals wherein the second correlation is minimized and the second output signals are maximally separated, 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.
