The problem of determining pore size and pore concentration In cast and weld material as well as in composites are of technological importance. In this paper analytical and experimental work is presented to correlate ultrasonic attenuation due to porosity in a solid body. From the spectral behavior of the attenuation coefficient both pore size and pore concentration ca be determined. The method is applicable if the total pore volume is less than 6% and if grain scattering is negligible.
