Abstract: Acoustic valve for a hearing device, including a valve body defining a passageway, and a seat member and shutter member inside the valve body. The shutter member defines a shutter surface that forms a contact portion and a non-contact portion. The shutter member is moveable relative to the seat member to transition the valve between an opened state, wherein the shutter member is removed from the seat member and the passageway is open to allow sound to pass, and a closed state wherein the contact portion abuts the seat member and the non-contact portion blocks the passageway to restrict passage of sound. The contact portion forms a protruding structure that extends from the non-contact portion and towards the seat member, and has a small width along at least one transverse direction to minimise a contact area between the contact portion and the seat member when the valve is closed.
