Noise barriers are often used to shield sensitive community areas from roadway, railway, and industrial racket. These structures are built based on the careful measurement of noise levels and environmental conditions.
Did you know that there are over 100 miles of barrier in the state of Maryland?
In our latest "Meet Our Readers" Q&A, Ken Polcak, Noise Abatement Design & Analysis Team Leader for the Maryland State Highway Administration, explains his work with transportation noise analysis and mitigation.
Polcak's experience centers on the acoustical design of noise barriers, computer prediction and modeling, field testing and research, and impact assessment.
