Method for operating a hearing device as well as a hearing device

A method for operating a hearing device by applying a frequency transposition scheme to an input signal (i) of the hearing device comprising an input transducer (1), a signal processing unit (3) and an output transducer (5), the method comprising the steps of:

• transforming the input signal (i) from time domain into frequency domain by applying a transformation function in order to obtain an input spectrum having a frequency range comprising a source region (20) and a destination region (30),
• adaptively selecting signal components of the source region (20) taking into account momentary characteristics of the input signal (i),
• transposing the selected signal components to the destination region (30), and supplying an output spectrum or a transformation thereof to the output transducer (5), the output spectrum comprising signal components of the destination region (30),
• wherein the source region (20) comprises a lower source region (21) and at least two source stacks (22, . . . , 26), the lower source region (21) being below a cut-off frequency (FC) and the at least two source stacks (22, . . . , 26) being above the cut-off frequency (FC), and wherein the destination region (20) comprises a lower destination region (31) and a destination stack (32), the lower destination region (31) being below the cut-off frequency (FC) and the destination stack (32) being above the cut-off frequency (FC), the cut-off frequency (FC) particularly being below 1,500 Hz, and wherein one of the source stacks (22, . . . , 26) is selected and transposed to the destination stack (32) by either replacing an original frequency content of the destination stack (32) with a frequency content of the selected source stack (22, . . . , 26) or combining the original frequency content of the destination stack (32) with the frequency content of the selected source stack (22, . . . , 26).
