Dr. Peter D’Antonio is a pioneering sound diffusion expert. He received his B.S. from St. John’s University in 1963 and his Ph.D. from the Polytechnic Institute of Brooklyn, in 1967. During his scientific career as a diffraction physicist, Dr. D’Antonio was a member of the Laboratory for the Structure of Matter, headed by Nobel Laureate Dr. Jerome Karle. As a musician and recording engineer, Dr. D’Antonio maintained a separate concurrent career in the music industry. In 1983, he founded RPG Diffusor Systems, Inc., to develop and test novel surfaces to expand the acoustical palette. He pioneered the sound diffusion industry and has significantly expanded the acoustical palette by inventing a wide range of novel number-theoretic, fractal, and optimized diffusing, absorbing, and metamaterial surfaces, for which he holds many trademarks and patents. He is the co-author of the reference textbook Acoustic Absorbers and Diffusers: Theory, Design and Application, 3nd Edition published by CRC Press (August 2016) and contributing author to the Master Handbook of Acoustics, McGraw Hill. Currently, Dr. D’Antonio is President/Founder of the Chesapeake Acoustic Research Institute, LLC (CARI), founded in 2007, and Director of Research at RPG Acoustical Systems, LLC and the Walter-Storyk Design Group. In 2019 Dr. D’Antonio joined with WSDG Founding Partner, John Storyk, and PK Pandey, to form REDIAcoustics.
