A hearing device adapted to be worn at or in an ear of a user, or adapted to be fully implanted in the head of the user or partially implanted in the head of the user where only a part of the hearing device is implanted in the head of the user, the hearing device comprising • an input unit for providing at least one electric input signal representing sound in a frequency sub-band representation (k, m), where k and m are frequency and time indices, respectively, • an SNR estimation unit for estimating a signal to noise ratio and/or a level estimation unit for estimating a level of said at least one electric input signal, or a signal or signals derived therefrom, in said frequency sub-band representation, • and a configurable frequency transposition unit (FL, CONT) for transposing content of a source frequency sub-band FB S into a destination frequency sub-band FB D so that the contents of the resulting destination frequency sub-band is determined as a weighted combination of the contents of the source and destination frequency sub-bands according to the expression P Dmod = αP D + βP S or MAG Dmod = αMAG D + βMAG S wherein P D and MAG D are the unmodified power spectrum and magnitude, respectively, of the destination frequency sub-band before frequency transposition, P S and MAG S are the power spectrum and magnitude, respectively, of the source frequency sub-band, and P Dmod and MAG Dmod are the resulting power spectrum and magnitude, respectively, in the resulting destination sub-band after the frequency transposition, and the parameters α and β are destination and source band weight factors, respectively, that specify details of the frequency transposition operation, and wherein • said configurable frequency transposition unit (FL, CONT) is configured to determine at least one of said weight factors α and β in dependence of said estimate of signal to noise ratio and/or said estimate of level of said at least one electric input signal, or a signal or signals derived therefrom. • an input unit for providing at least one electric input signal representing sound in a frequency sub-band representation (k, m), where k and m are frequency and time indices, respectively, • an SNR estimation unit for estimating a signal to noise ratio and/or a level estimation unit for estimating a level of said at least one electric input signal, or a signal or signals derived therefrom, in said frequency sub-band representation, • and a configurable frequency transposition unit (FL, CONT) for transposing content of a source frequency sub-band FB S into a destination frequency sub-band FB D so that the contents of the resulting destination frequency sub-band is determined as a weighted combination of the contents of the source and destination frequency sub-bands according to the expression P Dmod = αP D + βP S or MAG Dmod = αMAG D + βMAG S wherein P D and MAG D are the unmodified power spectrum and magnitude, respectively, of the destination frequency sub-band before frequency transposition, P S and MAG S are the power spectrum and magnitude, respectively, of the source frequency sub-band, and P Dmod and MAG Dmod are the resulting power spectrum and magnitude, respectively, in the resulting destination sub-band after the frequency transposition, and the parameters α and β are destination and source band weight factors, respectively, that specify details of the frequency transposition operation, and wherein • said configurable frequency transposition unit (FL, CONT) is configured to determine at least one of said weight factors α and β in dependence of said estimate of signal to noise ratio and/or said estimate of level of said at least one electric input signal, or a signal or signals derived therefrom.
