Through my careers in diffraction physics and acoustics for 5 decades, I have been privileged to know,
learn from, and collaborate with the brightest and most creative minds of my generation. I formed CARI, LLC to share this unique
experience with the architectural acoustics community by teaching and mentoring Master’s and Ph. D. students, publishing educational
articles, white papers and books, and consulting on fabric testing, new products and room designs and acoustical coefficient methodology and testing.
My mission is to provide acoustical exploration, experimentation, and education to the architectural acoustics community to minimize unwanted noise,
increase speech intelligibility, enhance music appreciation and share my three decades of experience in pioneering the sound diffusion industry as
founder of   RPG Diffusor Systems, Inc.
