Abstract:
1. An acoustic device which can be circumferentially mounted over a user's ear and held in place by the inward pressure created by the shape of the device, having a circumference smaller than that of a user's external ear, the device formed of moderately flexible material, the deformation thereof causing the internal pressure against the resisting outward force generated by the device's inward deformation of the external ear of the user, so that: a. the parabolic front-facing opening of said device permits sound wave radiation to enter the device where it mechanically reflects into the ear canal of the user greater amounts of these sound waves generated by sound sources faced by the user by means of reshaping and moving forward the pinna of the external ear of the user into a position that permits more of the frontal area of the pinna to reflect these sound waves into the ear canal; b. the combined shape of the interior surface of the user's concha and pinna and the inner face of the device phase-coherently concentrate these sound waves and direct them into the user's ear canal by more closely approximating the shape of an oblate spherical lune or diangle paraboloid; c. all linear sections of the rear portion at the junction of the lune or diangle paraboloid to the head of the wearer form an obtuse angle.
