发明名称 Hearing protection apparatus with incorporated eyewear
摘要 An apparatus for providing hearing protection to a wearer includes an incorporated set of eyewear having an eyewear frame. In one version, a pair of ear muffler tubes are coupled to the supporting members of the frame or made integral therewith, the muffler tubes each extending to the entrance of the ear canal of a person to reduce the level of ambient noise in the ear canal and includes at least one muffler tube of appropriate dimensions sufficient to isolate the ear canal from ambient air that substantially reduces the acoustic impedance at the entrance of the ear canal over a wide range of audible sound frequencies. A connecting tube for attachment to the ear canal is coupled to the ear muffler tube.
