PROJECT DESCRIPTION

City of Seattle Central Link Light Rail C755 Noise Barrier. .

SCOPE OF WORK

1800 acoustical panels were designed, fabricated and supplied for this project. 

NOISE SOURCES

The linear motor and the acceleration and deceleration of the braking systems on contact with the rails were the major noise sources.

SILENCING SOLUTIONS

Acoustic panels were designed with a curved profile in the vertical position and also to follow the curve of the elevated concrete guide-way. Panels were to be constructed of non-corrosive materials. The panels were fabricated from aluminum sheet material with a polyester powder coating and provided significant noise reduction. The acoustic panels were tested at STC 52.
