Abstract

Noise attenuator apparatus for use on a noise source including an exhaust inlet assembly using sound attenuators being equal to the exhaust pressure needs of the noise source whereby the sum total area of all smaller openings of the attenuators is equal to the exhaust volume needs of the noise source. Surrounding the inner or primary assembly, a sealed partition of any dimension containing an inner chamber which allows for the release of exhaust gas through any number of attenuators of which the smallest exit openings are equal to the exhaust volume needs of a noise source divided by the actual number of sound attenuators. The preceding assembly contained within this secondary chamber being contained or shrouded by an outer casing made from any number of plates or curved pieces whereby the primary and secondary chambers being contained by an outer casing through which the exhaust gas exits by way of measured openings or attenuators.
