E447 - 74 Standard Test Methods for Compressive Strength Of Masonry Prisms , ASTM E477 has been revised eight times since its establishment in 1973, with the last revision in 2006. When a specification reads “Must be tested in accordance with ASTM E477”, a loophole is left open for a manufacturer to provide a silencer tested by any set of ASTM E477 standards established since its inception. ASTM E-477 is the current standard test method used in North America for evaluating the acoustic and aerodynamic perfor-mance of duct silencers. The test method uses, at a minimum, a source chamber, a test duct (that includes a test specimen), and a reverberation chamber.
