May Meeting Notice

May 2003 Meeting Notice

The technology behind an ITU standard called PEAQ, or Perceptual Evaluation of Audio Quality will be presented. Opticom's founders, formerly of Fraunhofer Institute, have much experience perfecting the psycho-acoustic models of MPEG audio, which is fundamental in the objective perceptual testing methods that are largely replacing subjective listening tests. Their work has resulted in speech and audio testing standards which include PEAQ, and many companies including Dolby Laboratories have
gained experience using PEAQ in performing objective evaluation of audio quality. Mr. Benjamin of Dolby Laboratories will describe the experience Dolby has gained in using PEAQ. Also, Opticom will present a demonstration of testing with PEAQ technology.  Opticom received the AES Publication Award 2003 for PEAQ technology at the recent 114th AES Convention in Amsterdam. Preprints of this paper will be available at this AES Section Meeting.

Aart Konynenberg is Vice President of Business Development with Opticom Instruments Inc. Aart assists companies with their technology roadmaps, product verification and network design reviews. He also teaches, writes papers, and presents at many conferences. Before joining Opticom, Aart work for a number of T&M companies as Product Manager, Marketing Manager and Director responsible for a wide selection of Telecommunication and IP test equipment. He has represented Tektronix on numerous standards committees, including ANSI, IEEE and ITU. He holds several patents for measurement technologies in Telecommunications networks. Aart has had a long-standing interest in test as well as reliability, availability, and serviceability dating back to his time in the Airforce where he managed Radio Relay Communication networks.
