Swenson, George W. Rossi, Tyler J. 2010-08-20T18:00:30Z 2010-08-20T18:00:30Z 2010-08-20T18:00:30Z 2010-08 This is a study of the relationship between the measured acoustic parameters and the measured physical parameters of porous media. Materials studied include crushed limestone, stream-formed pea gravel, large and small sifted pea gravels, and glass spheres. A standing wave curve fitting algorithm was applied to data taken from a vertical impedance tube to determine the propagation and reflection parameters of the materials. Physical characteristics considered include porosity, tortuosity, and flow resistivity.
