Abstract
An audio amplification device such as a hearing aid equipped with a user-operable volume control that provides users with the facility to return the volume of the device to a specific level after having been adjusted to a different level by the user. The device includes an electronic module adapted to detect when the volume control reaches a pre-determined volume reserve position from a second volume position, and to emit a reference signal when the volume reserve position is reached. The reference signal may be an audible tone, or another type of distinct signal. The present invention may be adapted for use with binaural hearing aid fittings.
