适用范围：The document specifies a method for the simplified determination of the insertion loss of duct silencers intended for use with flows with velocities of 15 m/s or less. It is applicable for silencers with circular cross sections and diameters between 80 mm and 2000 mm and for silencers with rectangular cross-sectional areas in the same order of magnitude.
