Noise Control Engineering

Noise Control Engineering

Available in 1-day, 1.5-day, and 2-day formats

Description:

The most effective way to prevent occupational noise-induced hearing loss is through effective implementation of engineering noise controls. With some advanced education and training, it is feasible for industrial hygienists with a basic knowledge of the fundamentals of noise to develop noise control solutions; establish noise control priorities; identify and select optimum products for retrofitting equipment; work effectively with design engineers to implement a pro-active approach to noise control; and predict the impact new equipment will on the existing noise levels.

noisecontrol01Outcomes:

Upon completion of the course, attendees 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. Complete noise control design and retrofit applications for a variety of industrial equipment, such as pneumatic or compressed air systems, electric motors, fans or blowers, pipelines, panel radiated noise, etc.
4. Work effectively with design contractors, acoustical product suppliers, and consultants to achieve the stated noise criteria or goals.

Outline:
Principles of Noise Control • Workshop: Analyzing frequency data to Identify the Sources of Noise • Room Acoustics: Sound Propagation Inside Spaces • Acoustical Absorption • Sound Transmission Loss • Workshop: Estimating the New Sound Level after Relocating Equipment • Noise Control Options and Applications for Specific Equipment: Electric Motors, Vibration Isolation, Pneumatic and Compressed Air Systems, Pipe Radiated Noise, Acoustical Lagging, Machine Casing or Panel Radiated Noise, Vibration Damping, Industrial Fans, Enclosures, How to use Sound Absorption Materials, and Silencers. For 2-day or longer seminars, we offer an optional hands-on use of acoustical instrumentation. Plus, for courses conducted at a client facility, we can include a workshop on conducting a noise control survey inside the plant.

Instructional Methods:
The instructional method will involve presentation of multiple case histories to present the principles of noise control, and describe the various noise control applications and options for specific industrial equipment. Noise control demonstrations will be used to reinforce the concepts and proper use of acoustical materials. Several spreadsheet routines will be demonstrated throughout the lectures.

Learning Aids:
Several spreadsheet programs and significant references for noise control will be provided to each student, as well as demonstrated throughout the course. Hands-on workshops are also designed to enable the student to work comfortably with the spreadsheets, and confidently conduct a noise control survey, identify the sources of noise, and develop workable noise control solutions.
