Claim Text:
1. A listening device for a hearing impaired person being subjected to a tinnitus at a tinnitus frequency range comprising a tinnitus frequency, the listening device comprising an input transducer configured to provide an electric input signal comprising audio; a controllable filter for filtering the electric input signal received from the input transducer, the controllable filter being configured to output a filtered electric input signal such that signal energy of the electric input signal immediately surrounding the tinnitus frequency remain substantially unchanged and signal energy of the electric input signal at a distance to the tinnitus frequency is substantially reduced; a signal processor connected downstream of the controllable filter and configured to process the filtered electrical input signal according to a processing algorithm and to output a processed electric signal; and an output transducer connected downstream of the signal processor and configured to convert the processed electric signal to an acoustic output signal to be presented to a hearing impaired person wearing the listening device.
