ABSTRACT:
An apparatus for reducing the noise of coughs and sneezes by placement over the nose and mouth of the user. The apparatus has a core with a recessed portion to fit over the mouth and nose of the user and the core is made of a noise reducing material. A cover surrounds the core and has a section of absorbent material positioned over the recessed portion of the core. The noise reducing material of the core is a foamed resin.
