Project Experience: Chemical Plant Noise Study, Florida

The Challenge

Identifying noise sources and recommending solutions to noise problems related to activities at the Escambia chemical plant near Pensacola, Florida.

The Strategy

HHMH conducted an investigation that showed that plant noise levels in adjacent residential areas were generally acceptable, with the exception of a strong, low frequency component at 20 Hz. The noise appeared to originate from the exhausts of gas engines in the compressor building at the plant.

The Solution

Several potential noise control approaches were developed. These included:

  • Engine exhaust system re-design
  • Installation of in-line reactive exhaust silencers
  • Side-branch exhaust silencing systems or electronic sound cancellation systems
  • Residential improvements such as new or tightened windows and doors
