SCOPE OF WORK

INNOVA designed, supplied and supervised the installation of 1,200 meters of sound absorption panels for the northwest extension of the existing line. 

 

ACOUSTICAL REQUIREMENTS

Untreated noise level measured 74 dBA. Treated noise level 64 dBA.

NOISE SOURCES

The linear motor that is used for both acceleration and braking, and the wheel/rail contact were the two major sources of noise.

UNIQUE PROJECT HURDLES

The extension runs through an established residential area and the residents were extremely concerned about the noise impact of the LRT.
