Harness for suppression of hearing aid feedback
First Claim
1. A harness for mounting on a portion of a hearing aid which fits in an ear canal of a user, said harness comprising:
- a generally tubular member of resilient elastomeric material having a first end and a second end and a longitudinal centerline and having an opening in said first end which lies in a plane approximately perpendicular to the longitudinal centerline of the tubular member, and having an opening in said second end which lies in a plane which is at a substantial angle to the centerline; and
a notch in said tubular member located intermediate said first end and said second end, said notch extending substantially perpendicular to the longitudinal centerline.

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.

13. A harness for suppressing feedback associated with a hearing aid, said harness for mounting on a portion of the hearing aid which is placed in an ear canal a user comprising:
-
a first gasket; a second gasket coupled to said first gasket along a portion of a perimeter of said second gasket and said first gasket; and a tab coupled to said first gasket of a length sufficient to extend outside the ear canal of said user; whereby said tab is coupled to both said first gasket and second gasket such that the gaskets cannot fall off when the hearing aid is removed from the ear canal by pulling on said tab. - View Dependent Claims (14, 15, 16, 17, 18)

19. A harness for mounting on a portion of a hearing aid which fits in an ear canal of a user, said harness comprising:
-
a generally tubular member of resilient elastomeric material having a first end and a second end, a longitudinal centerline and a diameter, said material being sufficiently elastomeric such that the tubular member can be expanded radially of said centerline to a diameter sufficient to receive said portion of said hearing aid; and a notch in said tubular member located intermediate said first end and said second end, said notch extending substantially perpendicular to the longitudinal centerline. - View Dependent Claims (20, 21, 22)
