ABSTRACT:
An anechoic ear piece for placement about a human ear. The internal surface of the ear piece is lined with acoustic foam to prevent sound wave from reflecting off of the inner surface of the ear piece into the human ear. Furthermore, the ear piece is cone shaped with the apex of the cone adapted to lie opposite the listener's ear whereby sound waves entering the ear piece but not entering the ear itself directly, will impact on the inner surface of the ear piece wherein those waves not absorbed will be reflected toward other inner surfaces of the ear piece where continued absorption will take place.
