摘要：
Apparatus for protection of the ear and ear canal, and related methods of use and operation. In one embodiment, the apparatus includes a selectively actuated valve which permits a varying or modulated size of aperture to be created by the wearer while the apparatus is in use, so as to accommodate varying functions, such as complete occlusion (e.g., for use in swimming or other acquatic activities such that water can be completely excluded) or partial occlusion (e.g., such that sounds can be heard by the wearer, whether in air or under water). In one implementation, the apparatus is retained within the ear canal of the wearer by virtue of the apparatus' shape and coordination with one or more natural features or contours of the anatomy in the ear region, without having to be inserted more than superficially into the outer portion of the ear canal.
