Abstract: The present invention relates to a method for controlling a controllable acoustic valve of a hearing device, the controllable acoustic valve comprising a moveable valve element adapted to be positioned in one of at least two essentially stable states, wherein the moveable valve element is configured to be maintained in each of the essentially stable states by a retention force, and wherein a neutral point with essentially cancelling retention forces exists between the least two essentially stable states, the method comprising the step of providing a first drive signal to the controllable acoustic valve in order 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, wherein 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.

Abstract: The present invention relates to a self-biasing output booster amplifier (200) comprising an input amplifier stage (201), an output amplifier stage (206) being operatively connected to an output of the input amplifier stage, and first (203) and second (202) current copying circuits, wherein the second current copying circuit (202) is biased from an output of the self-biasing output booster amplifier (+). The first (203) and second (203) current copying circuits are configured to copy at least a portion of the current (Ios) through the output amplifier stage (206). The sum of the output of the second current copying circuit (202) and the output of the output amplifier stage (206) provides the output current (Isource - Io) of the self-biasing output booster amplifier (200), Finally, the input amplifier stage (201) is biased from the output of the second current copying circuit (202).
