Claim Text:
1. A hearing device adapted to be arranged on or at least partly implanted in an individual's head and comprising: an input unit providing one or more input audio signals in an audible frequency range; a signal processing circuit adapted to process at least one of said one or more input audio signals to provide a processed audio signal; an output unit adapted to provide an audible signal to the individual in dependence on the processed audio signal; one or more electrodes adapted to detect electric brain potentials of the individual; a brainwave measurement circuit adapted to determine one or more EEG signals from electric signals received from the one or more electrodes; a first spectrum analyzer adapted to repeatedly determine first spectra in the audible frequency range of at least one signal from the group of signals consisting of said one or more input audio signals and the audible signal; a reconstructor adapted to repeatedly reconstruct second spectra in the audible frequency range from the one or more EEG signals; a first coherence calculation unit adapted to repeatedly determine a first coherence between the first and the second spectra; and a control unit adapted to alter said processing in dependence on the first coherence.
