Abstract
A hearing device such as a hearing aid, ear pod, headphone, or other wearable is provided, whose components include the following: an acoustic transducer with a vent port operable to produce sound, a housing of the acoustic transducer with a sound opening, and an actuatable acoustic valve disposed in the housing, where the acoustic valve is actuatable to alter passage of sound through the acoustic vent to change the state of the hearing device between an open vent state and a closed vent state, so that actuation of the valve changes an acoustic characteristic of the hearing device.
