Drill rig noise levels
However, our extensive experience in this field has shown that drilling rigs tend to produce noise levels of 60 to 65 dBA at a distance of 500 ft from the rig. Effective noise control measures can significantly reduce sound levels. Reductions of 10 dBA or more are usually achievable. [pdf]FAQS about Drill rig noise levels
How much noise does a drilling rig make?
The overall noise levels depend on the actual equipment used on the rig. However, our extensive experience in this field has shown that drilling rigs tend to produce noise levels of 60 to 65 dBA at a distance of 500 ft from the rig. Effective noise control measures can significantly reduce sound levels.
How do you predict the noise impact of a drilling rig?
Perform calculations, or utilize noise modeling software to predict the noise impact at locations where compliance must be achieved. The predicted noise levels should be based on noise measurements conducted on the actual rig that will drill the wells.
What causes loud noise in a drilling rig?
Loud noises are caused by pumps and trucks. The methods for reducing the noise are similar to the methods for drilling rigs: All equipment should be maintained properly. Modern lower noise equipment can be used.
How to reduce noise from drilling operations?
These structures are designed with materials that absorb sound waves, rather than reflecting them, which significantly reduces the noise levels that reach the surrounding environment. Enclosures are another effective strategy for mitigating noise from drilling operations.
Why should you create a noise map for a drilling operation?
Once you have created a noise map for a drilling operation, you can introduce controls to start protecting workers against the problem noise. Using the maps, mitigation measures such as modifying or replacing equipment with quieter models can be taken.
Does drilling cause noise?
Drilling operations, whether for oil and gas exploration, construction, or mining, are notorious for generating high levels of noise that can have adverse effects on workers and nearby communities.

Low noise screw air compressor
With dozens of highly rated air compressors to choose from, it was a challenge to select the top performers for our hands-on tests. We considered brand names to an extent—after all, manufacturers such as Ca. While a reciprocating air compressor is quiet, a rotary screw air compressor is more silent. This air compressor has two separate helical screws working in unison to get the job done. Note that the two screws do not come in contact with each other, making them quieter. [pdf]
