Abstract
A self-cleaning cerumen guard includes a thermally activated element. The cerumen guard is mounted on the distal end of a hearing device adjacent to a sound port. The thermally activated element is oriented in a manner which causes it to retract when heated to a first temperature range and extend when cooled to a second temperature range, such that, upon removal of the hearing device from an ear canal, the self-cleaning cerumen guard will automatically remove any accumulated debris from the sound port.
