The East Carolina University Acoustics Laboratory was the site for the first-ever 3D measurements to register not only the sound-producing surface up-down vibrations, but also the in-plane (left-right, back-forth) motions using the Polytec 3D laser system. The acoustic radiation over a sphere was then measured in the Acoustic Lab anechoic chamber, followed by a comprehensive CT scan of all three violins by Dr. Claudio Sibata at the Leo Jenkins Cancer Center of the East Carolina University Medical School facility. Finally all three old-Italians were played at a group listening session by Ara Gregorian of the East Carolina University School of Music (along with two modern violins by Joseph Curtin and Sam Zygmuntowicz) to enjoy and comment on the differences.
