Abstract
The intent of the investigation is to try to characterize the nature of scattered acoustical energy off of the face of a concrete masonry unit with an atypical geometry. The nature of the tests conducted would be in accordance with the AES-4id-2001 document which pertains to the Characterization and measurement of surface scattering uniformity. The uniformity of scattering can be analyzed and can give one an indication of the diffusive properties of the test samples. The product for which the testing is proposed, as previously mentioned, is a modification of a concrete masonry unit. The product is not uniform in section, a fact which means a two dimensional analysis of scattering will not suffice. Instead, the distribution of reflected sound waves over a hemispherical shell will be examined.
