Environmental Noise Control Inc’s temporary sound barrier walls are typically installed either along the perimeter of the fracing site or adjacent to the frac trucks. For optimum environmental noise impact reduction, the sound barrier walls are positioned as close as possible to the frac trucks while allowing for access and adequate airflow. ENC’s STC-25-rated sound wall panels typically reduce equipment noise levels by 15 to 22 dBA on the sides of the equipment where the wall is installed. All temporary fracing sound control walls are pre-engineered to meet or exceed IBC wind and seismic loading requirements.
ENC’s sound wall panel system is constructed with 8-foot high by 20-foot long steel frames, and 8-foot high by 20-foot long STC-25 acoustic blankets mounted on each frame. Each blanket panel has a 1-foot wide sealing flap on the bottom and one side to provide acoustical sealing with the adjacent panels when installed.
The acoustical panels can be installed one panel high (8′ high), two panels high (16′ high), three panels high (24′ high), or four panels high (32′ high) and affixed to steel support poles or I-beams installed on 10-foot centers.
The acoustical panels are connected to the vertical support structures with connectors that allow quick installation and removal. Where site conditions do not allow for structural support augmentation, ENC offers a “K” rail-supported temporary sound control wall system.
