标准简介
Specifies a direct method and a comparison method for determining the sound power level that would be produced by a source operating in an environment at standard meteorological conditions corresponding to a characteristic impedance of [rho]c = 400 N.s/m[3] (where rho is the density of air and c is the speed of sound).
