ASTM E477 – Standard Test Method forLaboratory Measurements of Acoustical and Airflow Performanceof Duct Liner Materials and Prefabricated Silencers
1.1 This test method covers the laboratory testing of some of the acoustical properties of sound attenuating devices including duct liner materials, integral ducts, and in-duct absorptive straight and elbow silencers used in the ventilation systems of buildings. Procedures are described for the measurement of acoustical insertion loss, airflow generated noise, and pressure drop as a function of airflow.
