Zusammenfassung:	A method for controlling a controllable acoustic valve of a hearing device. The valve includes a moveable valve element adapted to be positioned in one of at least two essentially stable states. The moveable valve element is configured to be maintained in each of the essentially stable states by a retention force. A neutral point with essentially cancelling retention forces exists between the least two essentially stable states. The method includes providing a first drive signal to the controllable acoustic valve to overcome a retention force of a first essentially stable state in order to initiate movement of the moveable valve element from the first essentially stable state to a second essentially stable state. The provided first drive signal is capable of bringing the moveable valve element from the first essentially stable state and beyond a neutral point between the first and second essentially stable states.
