Hearing device (1) arranged on or at least partly implanted in an individual's head and comprising: an input means (3,4,5,6) providing one or more input audio signals; a signal processing circuit (7,8) to process at least one of said one or more input audio signals to provide a processed audio signal; an output means (10) to provide an audible signal to the individual in dependence on the processed audio signal; two or more electrodes (13,14,20) to detect electric brain potentials of the individual; and a brain-wave measurement circuit (15,21,25) to determine one or more EEG signals from electric signals received from the two or more electrodes (13,14,20), wherein the hearing device (1) further comprises: a first spectrum analyser (11,12) to repeatedly determine first audio spectra of at least one signal from the group of signals consisting of said one or more audio input signals and the audible signal; a reconstructor (16) to repeatedly reconstruct second audio spectra from the one or more EEG signals; a first correlator (17,18) to repeatedly determine a first coherence between the first and the second audio spectra; and a control unit (19) to alter said processing in dependence on the first coherence.
