ABSTRACT:
A generally tubular cylinder of resilient material such as a silicon rubber, for mounting over a hearing aid, or ear plug, so as to provide two gaskets which seal the hearing aid, or ear plug, against the skin of the ear canal and stabilize it against movement in the ear canal thereby suppressing acoustical feedback. The cylinder is further shaped to provide a tab which extends to the exterior of the ear canal so that it can be easily grasped by the user to remove the hearing aid.
One of the ends (or gaskets) of the hearing aid harness may be lengthened to extend beyond and away from that end of the hearing aid which houses the speaker.
