Temporary gas compressor and pipeline excavation operation noise barrier walls typically range in height from 16 to 32 feet and can be installed on one, two, three or all four sides of a gas compressor station to meet the sound control requirements of the site. ENC’s STC-25 modular acoustical wall panel system is designed to effectively block compressor noise from propagating into the surrounding environment while allowing for quick and efficient installation and removal. For optimum environmental noise impact reduction, the sound walls should be positioned as close as possible to the noise sources while allowing for access and adequate airflow. Our STC-25 rated sound wall panels typically reduce equipment noise levels 15 to 22 dBA on the sides of the compressor equipment where the wall is installed. All temporary gas compressor sound walls are pre-engineered to meet or exceed IBC wind and seismic loading requirements.

The ENC sound blanket walls are constructed with 8 foot high by 20 foot long steel frames with 8 foot high by 20 foot long STC-­25 acoustical blankets mounted on each frame. Each blanket panel has a 1 foot wide sealing flap on the bottom and on 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 specially designed connectors that allow quick installation and removal. Where site conditions do not allow for auguring of structural support, ENC offers a “K” rail supported temporary sound control wall system.
