Abstract
Air flow openings in a machine housing facilitate air exchange with a machine, but may become outlets for machine noise. In order to protect a machine from possibly damaging elements while facilitating air exchange and attenuating machine noise, the present disclosure includes a machine that is, at least, partially surrounded by a machine housing. An acoustic media grille is positioned adjacent to at least a portion of the machine housing. The acoustic media grille and the portion of the machine housing both define air flow openings that, at least partially, correspond with one another to form an at least partially unobstructed air flow path.
