Agenda

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, and
  • 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. This is practical, take back-to-the-job and implement type information. 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

Presenter Bio

Mr. Driscoll is President and Principal Consultant of Associates in Acoustics, Inc.  Besides directing the business administration of the company, his primary responsibilities include conducting engineering noise control surveys, data analysis, research, and recommendations for noise control. He conducts environmental and community noise surveys, as well as employee noise exposure assessments. Mr. Driscoll also teaches noise control and hearing conservation training seminars, which are customized to the particular needs of the client or attendees.  Toward professional certification, he is a registered Professional Engineer and a Board Certified Noise Control Engineer. He is a Past President of the National Hearing Conservation Association (NHCA), a Fellow Member of the American Industrial Hygiene Association (AIHA), past Chair of the AIHA Noise Committee, and he served a five-year term as a Council Member of the Council for Accreditation in Occupational Hearing Conservation (CAOHC). Mr. Driscoll is lead author of Chapters 9 and 15, “Noise Control Engineering,” and “Community Noise;” respectively, which are published in The Noise Manual, 5th Edition, by AIHA Press, and is one of the textbook editors. He also published the training manual “Noise – Measurement and Its Effects,” available through the British Occupational Hygiene Society. Finally, Mr. Driscoll has won several awards for outstanding lecturer at national conferences, and has taught multiple top-rated professional development courses.
