State regulators take a closer listen to gas compressor stations

From StateImpact, a reporting project of NPR Member Stations:

"...compressor stations can stay noisy for years– even decades. The facilities are necessary to process and transport gas through pipelines. When it comes to noise regulations, they’re governed by a patchwork of local, state, and federal rules."

"...the decibel level only measures loudness. But many other factors affect how noise is perceived—from its frequency, to the topography of the area, even the weather and wind speed on a particular day"
