Abstract
An apparatus preventing hearing loss having a body made of soft compliant material having first and second ends and a channel extending therethrough, an acoustically limp material adjacent one end of the body with the acoustically limp material having a hole therein aligned with the channel extending through the body, component film, or other structure covering or sealing the opening in the acoustically limp material. The film may be a high-strength polymer less than 10 micrometers thick. A plurality of channels may extend through the body and a plurality of corresponding holes may be provided in the acoustically limp material. The film covers or seals the holes in the acoustically limp material. The film may behave like a flap to close in response to high energy sound waves. The flap shuts from the high intensity shock wave. The body may have shape to fit in an ear canal.
