A simple and inexpensive sleeve assembly that is easy to apply to and remove from the distal end portion of a sound control device and can be adapted to provide circumferential contact with a user's ear canal to control sound delivered to that ear canal at a desired level, to provide a cerumen guard at the end of a sound deliver tube included in the sound control device, or to provide both of those functions. The sleeve assembly comprises a first layer of flexible material (e.g., sound attenuating slow recovery foam, closed cell foam, open cell foam, reticulated open cell foam, or non-foamed polymeric material depending on the requirements of the sound control device on which the sleeve assembly is used) having a periphery that can be adapted to make partial or complete contact with or conform to the car canal of a user into which the sleeve assembly is inserted, or to make little or no contact with that ear canal. A stiff resiliently flexible attachment member having a through opening is fixed to one surface of the first layer. The first layer of material can have a hole between its first and second surfaces aligned with the opening in the attachment member to afford movement of a…
