Sea-Tac Airport Central Terminal Expansion

Sea-Tac Airport Central Terminal Expansion

Fentress Bradburn - Seatac, WA

The Seattle-Tacoma International Airport underwent a vast remodel which included a large central open space. Greenbusch provided the audio and acoustical design for the central court as well as design for the remodeled concourse paging and background music systems. Requirements for the system included background music to common public areas, as well as zoned, prioritized paging functions to spaces in very different and sometimes challenging acoustical environments, while still providing high-intelligibility to all patrons.

Sound Transit Central Link RSIP

Sound Transit Central Link RSIP

The Jones Payne Group - Seattle, WA

Sound Transit, in partnership with the FTA, the State of Washington, and the Communities of the Rainier Valley & Tukwila, improved the quality of life for residents affected by noise from recently completed light-rail and traffic through its Residential Sound Insulation Program (RSIP). Potential noise impacts were identified for 137 residential buildings, primarily along MLK Jr. Way S. and in Tukwila. Greenbusch measured the sound transmission characteristics of each home, the results of which were used to develop the acoustical improvement packages. Improvements occurred in living areas of eligible homes and included replacement of exterior doors and windows and installation of ventilation and air-conditioning systems.

North Portland Environmental Noise

North Portland Environmental Noise Data Collection & Abatement Recommendation Project

City of Portland - Portland, OR

This two year noise study in the North Portland area documented the dominant sources of sound, including traffic, industrial and aviation noise as well as activity at the Portland International Raceway. The results of this study were presented as a computer noise model showing predicted sound exposure contours for each sound source and a composite of all modeled sources.
