Date: Tuesday, April 11, 2006
Time: 7:00 PM
Place: Critical Listening Classroom, Durgin Hall, Room 114, University of Massachusetts Lowell, 35 Wilder Street, Lowell, MA 01854

Featured Guest: Robert Crowley of Soundwave Research
Topic: The new Crowley and Tripp Ribbon Microphones

Robert J. Crowley (Bob) is the cofounder of Soundwave Research Laboratories Inc, of Ashland, MA --a medical instrument developer located in the same facility as Crowley and Tripp Microphones. Bob has designed transducers for ultrasonic and sonic applications, and has over 100 US and foreign patents and patent applications, mainly in fields relating to imaging, sensors, and nanotechnology. In this presentation, Bob will talk about design goals and methods his group uses to improve the sound quality of microphones. Examples will include some of Bob's laboratory findings and recent inventions in ribbon microphones.

There will be a detailed look at how the design goals are being implemented at Crowley and Tripp, as well as a close up look at new carbon nanotube array transducers being developed by Soundwave Research Laboratories.

Note that there will be no open forum, only a brief time for announcements, since this is an AES sponsored meeting.
