Beschreibung
Zusammenfassung:	Apparatus for reducing noise emitted from an appliance having a cabinet that supports at least one component that emits at least one acoustic pressure wave therefrom. In a preferred form, the apparatus comprises at least one diffuser having at least one deflection surface. The diffuser is coupled to the cabinet and positioned relative to the one component such that the acoustic pressure wave emitted from the component is deflected by the one deflection surface in a predetermined direction. The diffuser can be used to deflect acoustic pressure waves such that they collide with each other. The apparatus may further include at least one absorber. The diffuser is strategically located to deflect acoustic pressure waves being emitted from the component into the absorber to reduce the noise emitted from the appliance.
