Hearing device with brain-wave dependent audio processing.
2013 (English)Patent (Other (popular science, discussion, etc.))
Hearing device (1) adapted to be worn by an individual and comprising: a housing (2) arranged at an ear; an input means (3, 4, 5, 6) providing one or more input audio signals; a signal processing circuit (7, 8) processing at least one of said one or more input audio signals to provide a processed audio signal; an output transducer (10) providingt an audible signal to the individual in dependence on the processed audio signal; two or more electrodes (13, 14, 20) detecting electric brain potentials of the individual; and a brain-wave measurement circuit (15, 21, 25) determining 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) adapted 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) adapted to repeatedly reconstruct second audio spectra from the one or more EEG signals; a first correlator (17, 18) adapted to repeatedly determine a first coherence between the first and the second audio spectra; and a control unit (19) adapted to alter said processing in dependence on the first coherence.
