ARC - The Acoustical Research Center
The 𝐄𝐱𝐩𝐞𝐫𝐢𝐦𝐞𝐧𝐭𝐚𝐥 𝐌𝐞𝐚𝐬𝐮𝐫𝐞𝐦𝐞𝐧𝐭𝐬 𝐋𝐚𝐛 contains a 10,065 ft3 (285 m3) rev room, a 2'x2', 25' long, 7-ton low-frequency impedance tube, offering the capability of measuring absorption from 20-200 Hz, and a 6"x6" impedance tube to measure absorption and fabric transparency, between 63 and 4,000 Hz, using a single sample. It also contains a scale model boundary layer goniometer to measure the diffusion and scattering coefficients.
The new 𝐕𝐢𝐫𝐭𝐮𝐚𝐥 𝐒𝐢𝐦𝐮𝐥𝐚𝐭𝐢𝐨𝐧 𝐋𝐚𝐛 utilizes the first wave-based BEM virtual goniometer program, called VIRGO, to predict the diffusion and scattering coefficients of any shaped surface from a CAD file, eliminating the need to make prototypes.

The new 𝐕𝐢𝐫𝐭𝐮𝐚𝐥 𝐄𝐝𝐮𝐜𝐚𝐭𝐢𝐨𝐧 𝐋𝐚𝐛 allows us to provide collaboration with specifiers, as part of our ARC Associates Alliance program, and acoustical education in short LinkedIn posts with an extensive curriculum of topics derived from our 4 decades of research, publication, and books. We will describe how reflective, diffusive, and absorptive surface treatments scatter directionally and randomly incident sound and how RPG utilizes this knowledge to develop leading-edge innovative products in our Diffuse Reflections series.
