Environmental Noise Training
Noise Measurement, Noise Modeling, Noise Assessment

The 2 day Environmental Noise Seminar is intended for engineers, technicians and hygienists working in the fields of environmental, community, and/or Industrial noise measurement, analysis and control. 

We will review the fundamentals of acoustics, sound source characterization, and outdoor sound propagation based upon national and international standards and  guidelines.

Upon completion of the training, attendees will be able to measure, predict and assess environmental noise impact.   Classroom lectures will be supported by hands-on laboratories which focus on test instrumentation &  planning, digital signal processing, sound pressure &  noise modeling.

A $150 discount will be applied to all registrations / payments received 60 days prior to the seminar.
Course Outline

Course Outline

Fundamentals of Acoustics

  • Basic physics: definition of motion and the wave equation
  • Sound pressure, sound intensity and sound power
  • The decibel scale (adding/subtracting/ averaging
    sound levels)
  • Noise descriptors Lp, LI, Lw, Ln, Leq, Lm
  • Time weighting & frequency filtering
  • Near, far, free and reverberant sound fields
  • Time and frequency domain (octave and FFT) analysis
  • Measurement considerations
  • Wave propagation, sound spreading, rection,
    screening, sound refraction

Outdoor Noise Propagation

  • Principal formulas and methodologies
  • Transmission path attenuation (divergence, air absorption,
    screening and scattering reflections, ground effects, wind
    effects, meteorological stability)
  • Review of National & International guidelines/standards
    (ISO, VDI, GENERAL PREDICTION METHOD,
    CONCAWE, FHWA, ...)
  • Development of propagation models for rail, traffic,
    industry and leisure noise)
  • "Rules of Thumb" for outdoor noise analysis

Source Characterization

  • Point, line and area sources
  • Noise source emission (intensity and sound power)
  • Frequency spectrum (full and third octave band)
  • Interior sound pressure level, exterior sound power level
  • Sound radiation/directivity patterns
  • Steady state, transient and tonal sound sources
  • Measurement in accordance with ISO, ANSI and manufacturer standards

Demonstrations, Hands on Laboratory
and Outdoor Exercises

  • Sound power determination using sound pressure
    & sound intensity methods
  • Sound radiation/directivity determination using
    sound pressure & intensity methods
  • Community noise measurement and characterization
    based upon statistical descriptors
  • Development of a 3-D, computer generated
    acoustical model
  • Verification of the computer model with field
    sound pressure measurements
  • Noise level predictions and noise wall/berm
    design using the "verified" analytical model
  • Presentation of measured noise data, sound level
    diagrams and noise contours
