Module 1 - Course Introduction and Fundamentals of Sound (55 minutes):

The course format, available reference material, and description of the risk are covered in the introduction. Next, the foundation for the course is built by defining:

  • The properties of sound, such as frequency, wavelength, period, and amplitude.
  • The cause and effect of sound, including pressure and power.
    Methods for manipulating decibels, such as adding and subtracting decibels.
  • The human perception and response to sound.

Module 2 - The Principles of Noise Control (90 minutes):
The objective is to provide a comprehensive discussion of the five principles of noise control to enable students to effectively:

  • Conduct a noise control survey, 
  • Evaluate sound level data to identify the sources of noise, 
  • Prioritize sources for noise control,
  • Determine the most practical noise control options, and 
  • Select the appropriate acoustical products or materials for noise control.

Modules 3 & 4: Noise Control Options and Applications for Specific Equipment – Part 1 (55 minutes) and Part 2 (55 minutes):
The objective is to provide detailed information on engineering noise control options and applications for specific equipment to enable students to address a variety of noise control challenges. Each presentation for specific equipment contains succinct case history information on what causes the noise and what are the proven noise control measures, including selection of the appropriate acoustical products or materials. The course content provides practical information that one can bring back to the workplace and immediately implement. Parts 1 and 2 cover the following topics, respectively:

  • Part 1:
    • Using sound absorption material for attenuation, 
    • Electric motors, including cooling fan selection and retrofit options, 
    • Pneumatic or compressed air systems, such as air valves, solenoids, cylinders, and air guns 
    • Positive displacement blowers, principally roots blowers, and
    • Acoustical insulation, for items such as piping systems, machine casings, hopper bins, chutes and product transfer lines.
  • Part 2:
    • Panel radiated noise and vibration damping, 
    • Industrial fans, including selection, design, maintenance, and retrofit considerations 
    • The use of silencers, 
    • Acoustical enclosures, both commercially available products and in-house fabricated
    • enclosures, and how to enhance machine guarding to achieve an acoustical benefit, and 
    • A course wrap-up with concluding remarks to kick start your noise control program. 

Learning Outcomes

Upon completion of the course, students will be able to apply the noise control concepts to:

  1. Conduct a noise control survey, identify the noise-generating mechanisms, and prioritize items for noise control
  2. Develop feasible engineering controls through effective implementation of the principles of noise control
  3. Understand noise control design and retrofit applications for a variety of industrial equipment
  4. Work effectively with design contractors, acoustical product suppliers, and consultants to achieve the stated noise criteria or goals
