Abstract
A method performed by a hearing device comprising a first housing, a microphone, a speaker, and a first control system configured to control an active vent, the active vent comprising a vent canal and a valve member configured to block the vent canal when the active vent is in the closed state, and to allow passage of air through the vent canal when the active vent is in the open state, comprising: emitting an acoustic signal from the speaker; measuring a first transfer function of an acoustic feedback path between the speaker and the microphone when the active vent is expected to be in the open state; measuring a second transfer function of the acoustic feedback path when the active vent is expected to be in the closed state; and determining a status of the active vent based at least on the first and second measured transfer functions.
