Owner of an Olympic size, velodrome training facility (a velodrome is an indoor arena for high speed, track cycling consisting of steeply banked oval tracks consisting of two (2), 180-degree circular, steeply banked bends connected by two (2) straights).
KNC model STL-4, NOISEBLOCK™ barrier panels were manufactured of 16 gage solid outer skin and 22 gage, perforated inner skin with acoustic grade fill suitable for outdoor exposure, all material galvanized steel, Type G90. The tongue and groove panel connections allowed for quick installation and inherent drainage of rain water. The structural steel components were supplied as assemblies with a factory hot-dipped, galvanized finish. All products are cost effective and backed by KNC’s extensive, independently tested database and proven performance.
KNC model KCAL/2, 6-inch deep acoustic louvers were used for the balance. The structural steel support system was designed to readily accept the louvers similar to the method used to install the NOISEBLOCK™ barrier panels. This common attachment methodology made efficient for the installer to complete the project. Since the existing wall could not support the reaction forces of the base plates if mounted on top, the structural steel columns were designed to run behind the wall up from grade.
The final barrier dimensions were 162'-0" L x 31'-0" W x 6'-6" H extension.
The installed sound barrier wall yielded the necessary 12 dBA sound reduction. This was perceived by the residential neighbors and surrounding patrons as sounding half as loud as the untreated noise. Proper air allowed for proper equipment operation. The time-line was met. The architect and acoustical consultant praised the work and highly recommend KNC for future projects.
