Abstract
A device for providing a seal between a sound-blocking or sound-transmitting device, especially an 'in the ear' hearing aid, and the ear canal into which it is inserted. This device comprises a layer of polymeric foam, especially retarded recovery foam, that is applied to at least a portion of the canal-contacting surface of the hearing aid. A normally tacky and pressure-sensitive adhesive bonds the foam to the hearing aid, thereby rendering the device easily removable and replaceable by the user. In a preferred embodiment the hearing aid is sealed to the bony portion of the ear canal.
