Abstract
An improved sleeve for mounting on the distal portion of a hearing aid or other sound control device to provide circumferential contact to the ear canal of a person into which the device is inserted. A currently preferred embodiment of the sleeve comprises a foam cylinder having an axial hole therethrough, with a washer-like disc axially aligned with the hole in the cylinder, the inner diameter of the disc being approximately the same as that of the hole through the cylinder. A knob-terminated sound delivery tube on the device snaps into the disc. A plurality of these sleeves can be stored in a novel tray-like container that permits removal only when a snap fit has been achieved between the sound delivery tube and the plastic disc. Used sleeves can be removed and stored in a separate compartment of the container.
