Audio-Technica, a leading innovator in transducer technology currently celebrating “50 Years of Passionate Listening,” is proud to announce that the paper “On the Study of Ionic Microphones” and its writers were selected as the recipients of the “AES 133rd peer review paper award, signifying it as the “best paper of the show.” The paper, 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., was presented at a juried paper session at the 133rd AES Convention in San Francisco, California. Jackie Green stated, “We are honored and delighted to receive this recognition. Audio-Technica has been at the forefront of many technology paradigm shifts, yet historically we have published very little regarding our research. We look forward to taking a more active role in advancing the art and science of audio technology, and sharing this information with our distinguished peers.” 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. The paper reviews the experimental outcome of two ionic methods, and considerations given to resolve issues revealed by the study.
