133rd AES CONVENTION, SAN FRANCISCO, CA, October 27, 2012 — Audio-Technica (booth 705), a leading innovator in transducer technology currently celebrating “50 Years of Passionate Listening,” is out in full force at this year’s AES convention. While the company displays new products on the trade show floor, members of Audio-Technica’s management are sharing research in two key presentations.
On Saturday, October 27, 2012, Audio-Technica is presenting the paper “On the Study of Ionic Microphones” (Convention Paper 8745) at the juried paper session “Transducers.” Composed by Hiroshi Akino, Audio-Technica Corp., Japan, with Hirofumi Shimokawa, Kanagawa Institute of Technology, Japan, and Jackie Green and Tadashi Kikutani of Audio-Technica U.S., the paper encapsulates the following research:
Diaphragm-less ionic loudspeakers using both low-temperature and high-temperature plasma methods have already been studied and developed for practical use. This study examined using similar methods to create a diaphragm-less ionic microphone. This paper reviews the experimental outcome of two ionic methods, and considerations given to resolve issues revealed by the study.
Also on Saturday, Bob Green, Audio-Technica U.S. Director of Digital and Technical Wireless Engineering, is chairing the presentation “Wireless Frequency Wrangling at Large Events” as part of the live sound seminars. Panelists include Dave Bellamy, Henry Cohen, Peter Erskine, Chris Dodds, Steve Caldwell and Larry Estrin. This session covers the overall approach to RF coordination, preparation and setup for a large event. Topics discussed include microphones, in-ear monitoring and production communications with specific focus on antenna systems, frequency coordination, RF isolation, monitoring, verifying operation and procedures.
