Regulatory and Licensing Requirements vs. Community Response
Regulations
Federal – EPA, FERC State – DEP (Widely Varying) Local – Ordinance (Widely Varying or non-existent)
Licensing
Usually driven by compliance with regulations ‘Operable’
Community Response
Annoyance – Subjective Tonal content Steady or Impulsive
![Page 27: An Overview of Noise Control - Brooks Acoustics Overview of Noise Control.pdfAn Overview of Noise Control in the Power Industry - What is a Power Plant - Typical Noise Sources - Regulatory](https://reader033.vdocuments.mx/reader033/viewer/2022051801/5ada600f7f8b9a52528cbe7d/html5/thumbnails/27.jpg)
Noise Regulations
- Based on A-Weighted Levels
- Leq (Equivalent Noise Level)
- Ldn (Day-Night Noise Level)
- Sometimes Address Tones, Impulses
![Page 28: An Overview of Noise Control - Brooks Acoustics Overview of Noise Control.pdfAn Overview of Noise Control in the Power Industry - What is a Power Plant - Typical Noise Sources - Regulatory](https://reader033.vdocuments.mx/reader033/viewer/2022051801/5ada600f7f8b9a52528cbe7d/html5/thumbnails/28.jpg)
Noise Metrics T Leq = 10 Log (1/T) (Pa(t) / Po)2 0 where Pa = Instantaneous A-Weighted Acoustic Pressure
Po = 20 micro-Pascals Ldn = 10 Log ( 15/24 Pd + 9/24 Pn ) where Pd = 10(Leq(day)/10)
Pn = 10(Leq(night) + 10) /10

Conclusions
- ‘Power Plant’ describes many configurations and types of energy/power facilities
- Typical noise sources respond to conventional treatment strategies
- Compliance with noise regulations does not guarantee community satisfaction
