초록

A phased treatment noise suppression panel is provided for use in an exhaust duct. The panel consists of individual sections designed with specific modal attenuation characteristics and located axially within the duct in such a sequential order, with respect to the noise source, as to take maximum advantage of modal redistribution effects on overall noise suppression.
