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.
Fundamentals of Acoustics
Basic physics: definition of motion and the wave equation
Sound pressure, sound intensity and sound power

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
