Noise Mitigation Systems
Drilling/Exploration
Generally, temporary sound barriers are installed around the edge of the drilling location between a noise generating source and any sensitive surroundings. Principle's cost effective, temporary barrier system is designed to reduce drilling operations noise impact into the surrounding environment while allowing for efficient rig up/down time. Depending on the height and length of wall needed, most installations take as little as one day.
Temporary walls are offered in heights from eight feet to 32 feet in increments of eight foot increases. The most common is the 16 foot perimeter wall with rig floor and rig substructure treatments. This combination effectively addresses and mitigates the contributing noise sources of drilling operations.
The "PE 202" panel has a sound transmission loss value of STC-32. This will generally reduce equipment sound levels by 18 to 26 dB(A) where implemented.
Principle has experience sound reduction as high as a 30 dB(A) reduction at 90 feet from the barrier system. Using 2 sound meter simultaneously at an actual operating drilling location, with meter 1 recording sound levels at the source inside the temporary generator set barrier system and meter 2 recording sound levels directly on the other side of the barrier, then at distances of 30, 60 and 90 feet away a very impressive sound reduction was achieved (shown below on graph).
Compressor Stations/Production
Temporary compressor sound barriers are utilized around gas compression facilities to quickly meet specific sound control requirements. Principle has specifically designed the PE-C1 system to appear and perform as permanent sound control solutions.
Temporary compressor walls are offered in heights from eight feet to 32 feet in increments of eight foot increases. Designed for quick implementation, affixed to steel support posts or I-beams. The panels' exterior color can easily be made to meet our customers' needs, such as branding of company colors or meeting municipalities' specific requirements.
- The "PE-C1" panel has a sound transmission loss value of STC-35.
Principle 303- Site Specific Tuned Sound Wall System (Permanent)
Principle's 303 permanent sound control barrier was engineered to have excellent sound transmission loss (STC) characteristics complimented by highly absorptive surface properties to stop and remove gas compression noise. Our Principle 303 barrier wall was tested by a 3rd party accredited laboratory and yielded values of STC-40 and NRC-0.95. The most impressive property of the Principle 303 wall is the 97% absorption @ 125 Hz (low frequency noise); this is not considered in the calculation of the NRC value. Principle 303 Barriers were engineered and designed specifically for the low tones produced by large gas compressors. We have case studies available upon request.
