Evaluating Acoustics and Vibration in Buildings

Proper Acoustics

Whether it’s a recording studio, music and performing arts center, an experimental research laboratory, a commercial office environment, or a hospitality space, proper acoustics are critically important. Mechanical and electronic vibration from support equipment must be anticipated and mitigated to avoid unwanted disturbances in those spaces.

System noise and vibration can be a seen as a problem during commissioning or the operation of a facility, long after it can be effectively addressed. If you can detect these problems during the design phase, and incorporate the appropriate design and construction details, you’ll improve timeliness and financial efficiency, and ultimately the success of your project. 

Increase your understanding of noise criteria and noise control, octave band, measuring protocol, isolation methods, and offer solutions to both common problems, as well as the unique situations you may encounter.  The classroom lectures and discussion will be supplemented by a tour of the the performing arts center on the UW–Madison campus.

“I wanted an acoustics & vibration 101 type course and got it.  I feel I speak of the subject matter w/ more confidence & greater clarity … I got the overview I came for and plan to attend Libraries & Museums next year, when I can build on what was learned here.” 
—Sean, Heery International, Andover, Massachusetts

"Quality of the presenters was excellent. You assembled a great group, thank you...best course I've attended. Feel very fortunate to have the chance to learn from these individuals."
—David, UW–Madison FP&M, Madison, Wisconsin

"Improved knowledge base and gained more refined knowledge as well, re: sound waves, room acoustics, air handling units...broad and specific enough coverage of how the topics are related/interdependent was presented and supported."
—Angela, Kinetics Noise Control, Dublin, Ohio

“The topics learned here will help when troubleshooting noise concerns with customers, seeing whether vibrations traveling through the structure is the issue or if it’s through the air."
—Francois, The VMC Group, Bloomingdale, New Jersey

Curtis Eichelberger

Curtis Eichelberger, PE, is the Principal of Eichelberger Acoustics in Harrisburg PA, after working at the Johnson Controls Design Center where he was involved with the design and application of HVAC airside equipment. He has over 40 years experience in research, engineering and application of products relating to acoustic and vibration technologies. Before joining Johnson Controls, he was employed in a variety of positions with Emerson and Bruel & Kjaer instruments, where he was responsible for the application of acoustic and vibration measurement systems. Early in his career, he managed a noise control group with Gannet Fleming Consulting Engineers where he was responsible for over seventy projects relating to building noise and vibration control. Curt is a member of the Institute of Noise Control Engineering (INCE), and ASHRAE where he is presently serving on the Research Administration Committee and is an instructor with the ASHRAE Learning Institute. Curt received his B.S. in Electrical Engineering and M.S. in Acoustics from the Pennsylvania State University.

Richard Talaske

Rick Talaske, FASA, is the President and Principal Acoustics Consultant for TALASKE | SOUND THINKING in Oak Park, Illinois. During his 38+ years as a practicing acoustical consultant, he has worked nationally and internationally on the design or evaluation of hundreds of performance facilities. Rick is the acoustician of the new Mead Center on UW-Madison’s campus, that will be presented in the course and includes a concert hall, recital hall, and instrumental rehearsal room. Rick is a Fellow of the Acoustical Society of America and a past Chair of ASA’s Technical Committee on Architectural Acoustics. He is a graduate of University of Michigan (B.S. in Engineering, 1976) and Pennsylvania State University (M.S. in Acoustics 1979).
