Meeting Topic: Dennis Gagne: EASERA
Speaker Name: Dennis Gagne, University of Hartford B.S.E.E. Graduate and former Bose Engineer
Meeting Location: Mali I Auditorium, Dana Hall, University of Hartford, West Hartford, CT
On the evening of April 19, 2011, former University of Hartford B.S.E.E. graduate Dennis Gagne returned to the College of Engineering, Technology, and Architecture for a demonstration of AFMG's EASERA acoustical and electrical measurement software.
Dennis began with an introduction to acoustical measurement devices, focusing on the advantages of recent software and hardware developments. He then walked through the calibration process, explaining the use of microphone specifications, calibration units, and function generators to configure the software for correct operation. Using his self-designed loudspeaker system, Gagne showcased EASERA'S functionalities through a series of tests using pink noise, sine sweep, and maximum-length-sequence signals. The gathered data was used to analyze the impulse response and frequency response of the lecture hall. Clarity and speech intelligibility indexes were observed. Despite the high price of the demonstrated software bundle, Gagne expressed a sincere appreciation for the relative affordability of his modest measurement system.
Now working as an independent consultant, Dennis draws on thirty years of experience at Bose Corporation. Hartford AES thanks Dennis for returning to the University for his second lecture event.
This tutorial was a joint event with the University of Hartford Acoustical Society of America Student Chapter. For more information about Hartford Acoustics, visit http://uhaweb.hartford.edu/celmer/index.htm
