Acoustical Analysis & Design

ISE's staff is formally trained in the requisite fields of acoustics, fluid mechanics, and gas dynamics allowing us to analyze a problem at a much more technical level than our competitors. All work is structured to correspond with project siting, design sequencing, and applicable federal, state, and local ordinances and requirements.

Typical environmental noise and general acoustical services provided by ISE include:

  • Noise analysis for environmental impact studies compliant with CEQA, NEPA, EPA, and HUD.
  • Advanced acoustical modeling using various tools including the IS3 field propagation model.
  • Descriptive acoustics and contouring using GIS methods.
  • Underwater acoustics.
  • Roadway, rail, and airport land use compatibility noise studies.
  • FHWA Traffic Noise Model (TNM) assessments.
  • DoD Air Installation Compatibility Use Zone (AICUZ) noise studies.
  • FAA Integrated Noise Model (INM) assessments.
  • Master Plan acoustical assessments, General Plan studies and updates.
  • Industrial and construction worker noise analyses.
  • OSHA and Cal-OSHA dosimetry studies and hearing conservation programs.
  • Mitigation monitoring programs and systems.
  • Acoustical barrier design.
  • Spectral, octave-band, and sound power analyses.
  • Active and passive noise control technology.
  • Acoustical laboratory testing.

Featured Video Clip (Shock Wave)

A video taken by ISE showing the supersonic expansion of high pressure natural gas in a pipeline. 

The shock wave is clearly visible at the 1:00 min mark as a white cloud above the end of the pipe and produces an acoustic overpressure of close to 140 dB - which is as loud as a rocket engine.
