A method for operating a hearing device for being worn at least partially within an ear canal of a user, including an ear canal microphone, a filtering unit and an electrical-to-acoustical converter, capable of active occlusion control (AOC) and allowing the user to adjust the AOC functionality according to his or her preferences. The method includes picking up an ear canal internal sound at the microphone which provides a signal representative of the internal sound, filtering the signal with the filtering unit to reduce a perceived level of body sounds produced by the user, providing the filtered signal to the converter which outputs sound into the ear canal, and changing at least one setting or parameter of the filtering unit in dependence of a control signal, wherein the control signal is initiated by the user. Moreover, a hearing device adapted to perform the method is provided.

Method for operating a hearing device capable of active occlusion control and a hearing device with user adjustable active occlusion control

A method for operating a hearing device including an ambient microphone, a signal processing unit, a receiver and an ear canal microphone. The method includes steps of filtering the audio signal processed by the signal processing unit with a filter having a transfer function including a transfer function from an output of the receiver to an input of the ear canal microphone when the hearing device is turned on and being worn in an ear canal of the user, computing a difference between the audio signal picked up by the ear canal microphone and the filtered signal, and detecting a presence of own-voice of the user based on the difference. Furthermore, a hearing device including an own-voice detection unit is provided, which is adapted to perform the proposed method.
