Noise Impact Assessment

A Noise Impact Assessment (NIA) is an analytical examination of noise that emits from a facility, its significance relative to local regulatory limits, and what needs to be done to ensure the facility is in compliance.

man measuring noise

An effective NIA will include the following steps:

  1. Specialized technicians take specific and detailed measurements of various noise sources at a facility.
  2. The sound power data received is derived from the existing onsite equipment manufacturer’s data, sound pressure measurements, or theoretical calculations.
  3. A report is produced that provides accurate noise levels that may be out of compliance and impacting a specific radius from the facility and nearby residents.
  4. A detailed Source Order Ranking Table is provided identifying and prioritizing the loudest noise sources that require attenuation.
  5. A Permissible Sound Level (PSL) is established based on distance, dwelling unit density & proximity to transportation corridors along with engineered noise control recommendations.

“I’ve been wanting to say “thanks” for the excellent work your Noise Solutions Team did in reducing the sound levels throughout the Shuttle Crawler Transporters. We had the opportunity to roll Shuttle Atlantis to the launch pad twice and I had the opportunity to experience first-hand the reduced noise levels due to your new Mufflers & Acoustical Ventilation Systems”

“Noise Solutions Inc. proved they could set up an engineered solution, they could guarantee it, and stand by it and in the end all of our targets that were set as objectives were met, measured, and proven to be true.”

“Our goal was to put 1445 horse power worth of compression on the Caroline Gas Plant without adding any noise to the existing ambient noise that came from the plant. I thought it was a pretty steep goal, but the acoustical assessment and Noise Solutions said it was achievable, so that seemed like the best viable option to go for. We did it and we met the goal of zero adder. Our operators were telling me later, when you stand outside the door in that building on the platform you couldn’t tell whether the compressor was running or not. So that’s pretty fantastic, really!”
