A hearing device comprising - a housing configured to be at least partially inserted into an ear canal, the housing surrounding a volume through which a venting channel extends, the venting channel configured to provide for venting between an inner region of the ear canal and an ambient environment outside the ear canal, - an acoustic valve comprising a valve member moveable relative to the venting channel between different positions including a first valve position and a second valve position such that an effective size of the venting channel can be modified by a movement of the valve member between the different positions; - an actuator configured to provide an actuation force with a direction and a magnitude acting on the valve member , wherein said direction includes a first direction for actuating the movement of the valve member from the first valve position to the second valve position, and a second direction for actuating the movement of the valve member from the second valve position to the first valve position; and - a controller configured to provide a first control signal controlling the actuator to provide the actuation force in the first direction, and to provide a second control signal controlling the actuator to provide the actuation force in the second direction, characterized in that the controller is configured to provide a predetermined temporal sequence of signal pulses controlling the actuator to provide the actuation force during a duration of each signal pulse, wherein said subsequent signal pulses are separated by an intermediate time interval during which the actuator is controlled to decrease the magnitude of the actuation force as compared to the magnitude controlled during the duration of each signal pulse , and the controller is configured to successively increase the duration and/or a signal level of the signal pulses in said temporal sequence. - a housing configured to be at least partially inserted into an ear canal, the housing surrounding a volume through which a venting channel extends, the venting channel configured to provide for venting between an inner region of the ear canal and an ambient environment outside the ear canal, - an acoustic valve comprising a valve member moveable relative to the venting channel between different positions including a first valve position and a second valve position such that an effective size of the venting channel can be modified by a movement of the valve member between the different positions; - an actuator configured to provide an actuation force with a direction and a magnitude acting on the valve member , wherein said direction includes a first direction for actuating the movement of the valve member from the first valve position to the second valve position, and a second direction for actuating the movement of the valve member from the second valve position to the first valve position; and - a controller configured to provide a first control signal controlling the actuator to provide the actuation force in the first direction, and to provide a second control signal controlling the actuator to provide the actuation force in the second direction, characterized in that the controller is configured to provide a predetermined temporal sequence of signal pulses controlling the actuator to provide the actuation force during a duration of each signal pulse, wherein said subsequent signal pulses are separated by an intermediate time interval during which the actuator is controlled to decrease the magnitude of the actuation force as compared to the magnitude controlled during the duration of each signal pulse , and the controller is configured to successively increase the duration and/or a signal level of the signal pulses in said temporal sequence. <EOS>
