Abstract
Embodiments relate generally to noise reduction techniques and systems for use with supplied air respirators. Typical embodiments may comprise porous elements located within a respirator system operable to alter the air flow pattern through the system and therefore reduce noise created in the system. These porous elements might be located within an inhalation valve, a breathing hose and/or a muffler block housing of a respirator system.
