System-wide OBSI study to evaluate success of diamond grinding to attain project noise reduction goal

J. Eric Cox

Eric Cox has more than 15 years of experience in environmental noise and vibration analysis across aviation, rail and transit, highway, wind energy, and industrial applications. Since joining HMMH in 2007, he has developed extensive expertise in noise and vibration measurement, data analysis, and instrumentation.

Eric has been heavily involved in airport sound insulation programs nationwide, supporting residential and non-residential facilities including homes, schools, hospitals, and other institutional buildings. His work includes acoustical measurements and modeling, evaluation of noise level reduction, and development of acoustic design criteria. He has also contributed to multiple FAA-funded research studies focused on improving sound insulation testing methods, evaluating mitigation effectiveness, and developing best practices for airport noise programs.

In addition to aviation projects, Eric has supported noise and vibration studies for rail and transit systems, highways, wind energy facilities, construction sites, and industrial operations. His experience includes On-Board Sound Intensity (OBSI) testing for quiet pavement studies, wind turbine compliance monitoring, and vibration mitigation assessments for rail and transit projects. He currently manages HMMH’s instrumentation laboratory, where he oversees measurement applications, analysis methods, and staff training, and has provided noise monitoring training for airport noise offices nationwide.

Eric holds a B.A. in Mathematics, summa cum laude, from Berea College and has completed graduate coursework toward an M.S. in Applied Physics at Northern Illinois University.
