Abstract
Iron slag, by-product of smelting iron ore, has been widely recycled to road pavement material and concrete for environmental-friendly effect. In the present study, the acoustical characteristics of iron slag panels (porous media) were investigated by using scale model approach. The scale models of the iron panels were constructed by considering different sizes of slags. The measurements of absorption and scattering/diffusion coefficients using scale models were conducted in a 1:10 scale reverberation chamber. Through the measurements, the effects of diameters and thicknesses of slags on acoustical properties of iron slag panels were investigated.
