Abstract
Methods and apparatus determine the actual state of one or more acoustic valves e.g., whether an acoustic valve is open or closed, in a hearing device. A sensor in the hearing device is configured to generate an output signal indicative of a state of the acoustic valve. An electrical circuit actuates the acoustic valve if the actual state is different than a desired state. The determination of the state of the acoustic valve can be done on the hearing device or on a remote device.
