When David Herrin came to the University of Kentucky to obtain his Ph.D., he was interested in anything that involved finite element analysis and modeling. Eventually, that led him to the field of acoustics. Today, Herrin’s experimental acoustics team conducts research in an Eckel anechoic chamber—a highly controlled environment for making noise measurements. Perforated metal wedges house fibers that absorb sound so that almost no noise is reflected from the walls back to the source. Upon entering the chamber, visitors often exclaim “Whoa!” only to discover the unique environment has significantly muted their surprise.
Herrin’s research is part of an ongoing partnership with the 20+ member Vibro-Acoustics Consortium. Twice a year, consortium members gather for presentations that specialize in noise and vibrational control for heavy equipment, engines and HVAC products. Membership in the consortium has doubled in the last 10 years.
