Abstract
Provided is a hearing device including a housing configured to be at least partially inserted into an ear canal of a user, a vent that provides venting between an inner region of the ear canal and the ambient environment, an acoustic valve with a valve member configured to adjust the effective size of the vent, an actuator that actuates the valve member, and an acoustic output transducer acoustically coupled to the inner region of the ear canal and configured to generate a sound output according to an audio signal. The hearing device further includes a control unit operatively connected to the actuator and the acoustic output transducer and configured to control the audio signal supplied to the acoustic output transducer such that the sound output is modified during adjustment of the valve member.
