Noise and Vibration Control for Airports

South Terminal Expansion Project, Sea-Tac Int'l Airport
NBBJ

Our project involvement included an extensive assessment of aircraft noise involving over 200 hours of site monitoring to develop specific recommendations for wall, window and roofing assemblies to achieve specific interior noise level requirements.

With our combined talents of architectural and engineering acoustics, we were able to go from our assessment to mitigation recommendations as part of the project team. We worked closely with the team at NBBJ to design recommendations for interior room absorption within the lobby, meeting rooms, open office areas, concourses, and private offices.

Wall type recommendations to control noise between exercise spaces, HVAC mechanical spaces, and emergency diesel generator spaces were provided. Our initial studies to measure noise levels from aircraft were later used to develop detailed recommendations for window and wall systems to the concourse and new terminal building.

Detailed evaluations were completed for mechanical systems serving the concourse and terminal building were developed by separate HVAC design firms.
