ABSTRACT:
A protective plug for sealing the ear canal has a tacky adhesive surface which when pressed against the skin attaches the plug temporarily in place. Retention of the plug does not rely on friction developed by compression of the body of the plug as it is inserted in the ear canal, and therefore the plug need not fit tightly into the ear canal and in some cases the plug may merely overlie the mouth of the canal. The adhesive surface may be a layer of adhesive applied to a substrate or it may be the surface of a body of plug material which is inherently tacky. The plug can be modified to transmit sound well while excluding water or to minimize sound transmission.
