Abstract
A hearing device comprises a) an input unit for providing at least one electric input signal representing sound in a frequency sub-band representation, b) 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, and c) a configurable frequency transposition unit for transposing content of a source frequency sub-band FBinto a destination frequency sub-band FB. The contents of the modified 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 c1) P=αP+βPor c2) MAG=αMAG+βMAG, wherein Pand MAGand Pand MAGare the unmodified and modified power spectrum and magnitude, respectively, of the destination frequency sub-band, and Pand MAGare the power spectrum and magnitude, respectively, of the source frequency sub-band, and the parameters α and β are destination and source band weight factors, respectively, that specify details of the frequency transposition operation. The weight factors α and β are determined in dependence of the estimate of signal to noise ratio and/or the estimate of level.
