Environmental Noise Seminar - Measurement, Modeling Prediction & Analysis

3 Day Environmental Noise Seminar:

Schedule:  April 12th-14th, 2010 & September 27th-29th, 2010
Course Fee: $1,850.00 per Attendee
The course fee includes participation, course notes, lunches and refreshments. A full refund will be made for all cancellations received 30 days before the start of the course. No refunds will be granted after the 30 day deadline. Substitute attendees will be accepted at any time. In the event that we have to cancel the course, the course fee will be refunded in full, but we disclaim any further liability.

The attendees are welcome to bring their own equipment, structure or product.

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, reflection,
    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
