Bio as of Feb. 2008

Don Keele has worked for several companies in the area of loudspeaker R&D and measurement technology including Electro-Voice, Klipsch, JBL, Crown, and Harman. He holds three patents on “constant-directivity” loudspeaker horns, has four patents pending, and is a fellow of AES and a member of ASA. He wrote for Audio Magazine as a Senior Editor performing loudspeaker reviews. More recently, he worked for Harman/Becker Automotive Systems in the advanced technology development group and was a member of the Harman corporate acoustics engineering group working under Floyd Toole. Currently he is back at Harman/Becker working in the simulation and virtual acoustics group.

Mr. Keele holds two BS degrees in EE and physics from California State Polytechnic University and an MSEE degree from Brigham Young University. He has presented and published over 35 technical papers on loudspeaker design and measurement methods and other related topics, among them the paper for which he won the AES Publication Award, “Low-Frequency Loudspeaker Assessment by Nearfield Sound-Pressure Measurement”. He is a frequent speaker at AES section meetings and workshops, has chaired several AES technical paper sessions, and is a member of the AES review board. Mr. Keele is a past member of the AES Board of Governors and is past Vice President, Central Region USA/Canada of the AES. Mr. Keele received the TEF Richard C. Heyser Award in 2001. In 2002, he received a Scientific and Engineering Academy Award from the Academy of Motion Picture Arts and Sciences for work he did on cinema constant-directivity loudspeakers.
