“Teach Your Children Well” Education has always been an implicit part of RPG®’s mission to provide continuous acoustical innovation through a commitment to fundamental research. Whether through industry seminars, workshops, or technical presentations for AES, ASA, CEDIA, Mix Sound Pro, NSCA, Syn-Aud-Con, and others, peer review journals, acoustical research publications, magazine articles, book chapters, or formalized educational classes, RPG® has attempted to give back to the industry that has supported its mission. November was a particularly busy month for this endeavor. For the past ten years I have been an adjunct professor at the Cleveland Institute of Music. Undergraduate students have contributed significant research in performance and practice room acoustics. We recently documented the modal response in individual practice rooms in an effort to minimize modal emphasis. Students are beginning to investigate anechoic recording of musical instruments for auralization research. Recently, I began teaching in the Peabody Conservatory of Music Masters Program. Topics include sources of acoustic distortion, the acoustic tool palette, characterizing diffusing surfaces, room acoustic measurements, and auralization. The first semester classes were held at RPG® and students were exposed to our diffusion coefficient measurement system and manufacturing facility. On November 6th Dr. Christopher Jaffe and the students of his new Sonics in Architecture class at Rensselaer Polytechnic Institute, Troy, NY, visited RPG® for an acoustics seminar and a tour of our research and manufacturing facilities. We will continue our involvement with this program and look forward to collaborating with the students on their individual projects. Several of these projects were discussed in class. Teaching is certainly time consuming, but it is time well spent as one cannot measure the rewards in playing a small role in the future of our students and the acoustics community. I am continually in awe of the dedication and discipline of these students and their families to their music education and how they enrich our society. Journal of the Audio Engineering Society In December, the Journal of the Audio Engineering Society is publishing a review article by Dr. Peter D’Antonio and Dr. Trevor Cox entitled Two Decades of Sound Diffusor Development, Part II: Prediction, measurement, and characterization. Abstract The last twenty years has seen great developments in the prediction, measurement, and characterization of diffusing surfaces. This paper reviews methods available for predicting and measuring the scattered polar distribution using Boundary Element Methods and Maximum Length Sequence stimuli. The current methods used to characterize the quality and amount of diffusion produced by a surface are described, including diffusivity, diffusion coefficients derived from predicted and measured polar distributions, and scattering coefficients derived from direct measurements. |
