Abstract: The present disclosure relates to communication devices. Such devices may comprise 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. Such processing may be 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 may comprise 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.
