1. An article of head wear comprising:
a shell having a upper portion and a lower portion; at least one aperture located near the lower portion; and a noise reduction plate obstructing the at least one aperture, wherein the noise reduction plate comprises:
at least one noise reduction element having a first edge; said noise reduction element further comprising a frame having framework, said noise reduction element further comprising a sound proofing element separate from the frame having framework, wherein the sound proofing element covers the framework; anda mount plate having an outer edge wherein at least a portion of the outer edge of the mount plate is substantially similar in contour to at least a portion of the noise reduction element's first edge, and wherein the outer edge of the mount plate is formed to slideably receive the noise reduction element and engage with at least a portion of the first edge of the noise reduction element, wherein a surface of the noise reduction element is substantially even with a surface of the mount plate when the noise reduction element is slideably engaged with the mount plate. |
