Abstract

A hearing aid is provided. The hearing aid comprises an input unit. The input unit is configured to provide a first frequency domain signal comprising a plurality of first frequency components associated with a first frequency range. The first frequency range comprises a first primary frequency range and a first secondary frequency range. The first frequency-domain signal comprises one or more first aliasing artefact frequency components. The first secondary frequency range of the first frequency domain signal comprises at least one first secondary aliasing frequency component of the one or more first aliasing frequency components. Each of the one or more first aliasing artefact frequency components is indicative of a frequency component of the plurality of first frequency components including a first aliasing artefact. The input unit is configured to provide a second frequency-domain signal comprising a plurality of second frequency components associated with the first primary frequency range. The second frequency domain signal comprises one or more second aliasing artefact frequency components. Each of the one or more second aliasing artefact frequency components is indicative of a frequency component of the plurality of second frequency components including a second aliasing artefact. The hearing aid comprises a signal processing unit configured to determine an aliasing artefact reduced signal based on the first primary frequency range of the first frequency domain signal, the second frequency domain signal, and the one or more second aliasing artefact frequency components. The hearing aid comprises an output unit configured to output, based on the aliasing artefact reduced signal, an audible signal to the user wearing the hearing aid.
