ABSTRACT:
An engine enclosure is disclosed having improved sound attenuating capabilities. The enclosure includes side panels, a front and rear and top and bottom thereof which define the engine area. Doors in the side panels permit access to the engine compartment for service thereof. Sound attenuating material is fastened to the inside surfaces of the side panels, doors and rear fire wall members. Acoustic baffles cooperate with the attenuating material to attenuate noise emanating from the engine compartment. Openings in the members permit flow of air into the engine compartment to satisfy engine cooling requirements. Sealing means cooperating between adjoining members provide for further sound attenuation.
