A HEARING ASSISTANCE DEVICE WITH BRAIN COMPUTER INTERFACE

The present disclosure relates to hearing aid devices comprising input for receiving sound signal to be processed and presented to a user, and output for outputting the processed signal to a user perceivable as sound. The processing is performed by use of a processor for processing the sound signal in dependence of a setting or a set of setting to compensate a hearing loss profile. Further, the communication device comprises a bio-signal acquisition and amplifier component in communication with a user interface for providing the bio-signals as input to the user interface, the user interface controlling the setting or set of setting for operation of the communication device. The bio-signal acquisition and amplifier component may comprise an ear EEG electrode configured to be inserted into an ear canal or on a skin-part of the head of a wearer or an implantable EEG electrode configured to be placed under the skin at the head and/or skull of a wearer or an implantable EEG electrode configured to be placed on the ear canal and the hearing aid device is configured to analyse EEG signals from the bio-signal acquisition and amplifier component to assist the feedback cancellation system in deciding whether a howl-like sound should be attenuated or not. Alternatively, the bio signal may be analysed for recognising an intended space gesture, which is translated into an input for the user interface.
