Abstract
Methods and apparatus change operation of a hearing device based on a state of an acoustic valve in the hearing device. In some examples an electrical circuit performs one or more of differing operations depending on a state of the acoustic valve. Some operations change the signal to a sound producing transducer and other operations change other operations of the hearing device. For example, an electrical circuit changes active noise cancelling operation, changes equalization settings, provides noise reduction improvements, provides beam forming changes and other operations based on a state of the acoustic valve. In some implementations, a change in acoustic valve state is used to change the operation of the hearing device.
