Noise Control Engineering LIVE Virtual PDC

Thank you

This live web event has ended. Thank you for attending.


Noise Control Engineering provides practical training on identifying and mitigation common noise sources in an industrial environment. Building on foundational concepts like A-weighted sound levels and octave bands, participants will be trained to conduct noise control surveys, identify noise-generating mechanisms, and develop engineering controls. The curriculum covers principles of noise control, room acoustics, sound transmission loss, and specific noise control strategies for industrial equipment such as electric motors and pneumatic systems. Instruction will include basic theory, analysis of case studies, and hands-on exercises. The course is tailored for industrial hygienists and professionals aiming to implement engineering noise controls in occupational settings.

Course Outline

  • Principles of Noise Control
  • Room Acoustics: Sound Propagation Inside Spaces
  • Acoustical Absorption
  • Sound Transmission Loss and Acoustical Barriers
  • Noise Control Options and Applications for Specific Equipment:
    • Electric Motors
    • Pneumatic and Compressed Air Systems
    • Machine Casing or Panel Radiated Noise
  • Industrial Fans and Blowers
  • Vibration Isolation and Damping
  • Enclosures
  • Silencers

Learning Objectives
After this virtual PDC, participants will be able to:
  • Conduct a noise control survey in an industrial environment
  • Select the correct metrics for noise and noise exposure measurements (e.g. SPL, Leq, dBA, TWA, octave bands, FFT)
  • Relate sound level measurements to noise dosimetry
  • Identify primary and secondary noise sources with respect to worker noise exposure
  • Develop noise mitigation strategies tailored to specific noise sources
  • Apply understanding of noise emission from machine operation to develop source treatment strategies
  • Apply understanding of noise transmission and material acoustic properties to develop path treatment strategies such as barriers and enclosures
  • Apply principles of room acoustics to develop room treatment strategies
