Chief advisor of US Sound and Vibration Institute



Dr. Chung performed more than 950 CEQA/NEPA related and stand-alone noise studies for community and transportation noise analyses, including field measurement, modeling, and data analysis. Typical noise analysis includes construction, vehicular traffic, and long-term stationary source operations. Others include rail, airport, and shooting range noise impact analysis.

Dr. Chung performed more than 750 air quality studies for projects such as transportation facilities, landfills, office buildings, and ocean bay enhancement/sediment management projects.

Dr. Chung conducted the design and analysis of architectural room acoustics (interior configuration and absorption required for proper room use) for more than 20 theaters, studios, workshop places, and convention centers.

Dr. Chung performed more than 80 acoustical analyses on building interior sound and vibration isolation for hospitals, apartment complexes, office buildings, performing arts centers, schools, etc., throughout the United States.

Dr. Chung prepared more than 40 greenhouse gas/climate change impact analyses. He monitors State and federal standards, case law, and scientific research to make sure that his analyses reflect the rapid changes in this evolving field. He works with clients to develop a customized approach to global climate change analysis that not only meets, but anticipates regulatory expectations.
