摘要:
There is provided an audio listening device comprising a housing, shaped to substantially form a pressure seal between an auditory canal of an ear and an external surroundings. A pressure relay channel in the housing is arranged for relaying a pressure difference between the auditory canal and the external surroundings. A pressure valve in the pressure relay channel is arranged for switching between an open or closed position for allowing or preventing, respectively, an exchange of pressure. An acoustic generator between the pressure valve and the auditory canal is arranged for generating an acoustic signal into the auditory canal. A pressure sensor is arranged for measuring an internal pressure level in the auditory canal and control logic is arranged for controlling an actuator to switch the pressure valve to an open position when the measured internal pressure level is above a threshold pressure level.
