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.
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.
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.
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.
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.
An effective hearing conservation program, when properly designed, implemented, and maintained, will
significantly reduce the potential risk to employees by preventing permanent noise-induced hearing loss
which results from overexposure to workplace noise. This seminar will help guide health and safety
professionals, occupational nurses, and management through the intricate details of an effective
hearing conservation program.
The course material may be custom designed to address the specific environment of the client's facility;
as well as provide employees and management useful information on each aspect of the hearing
conservation program, pertinent noise regulations, the harmful effects of noise exposure, the proper
use and care of their hearing protection devices, the annual audiometric testing program and data
Upon completion of this training course, the attendees will understand:
The fundamentals of sound, the properties of sound generation, propagation, and worker noise exposure.
Requirements for hearing conservation, based on local regulation and/or internal company policy in effect.
How to conduct a noise survey and determine worker noise exposures.
Basics of noise control engineering.
How to select and properly fit hearing protection.
Innovative and entertaining approaches to hearing conservation education and training.
Implementation of an audiometric testing program.
How to evaluate the program effectiveness through hearing test data analysis.
Overview of a Hearing Conservation Program • Noise survey and exposure determination • Reducing
noise exposures with engineering and/or administrative controls • Hearing protection devices, selection,
fitting, and evaluating effectiveness • Education and training • Audiometric testing program • Evaluating
program effectiveness through audiometric database analysis.
The United States Congress intended that states and cities retain primary responsibility for control of community noise when it passed the Noise Control Act of 1972. This has resulted today in a diversity of noise regulations among local communities and states, as well as in many locations that lack any noise ordinances at all. The widely varying approaches to regulating noise in communities pose a significant challenge to companies that operate multiple facilities, and to the people charged with the responsibility to assess compliance with those regulations.
A health, safety, and environment professional may need to evaluate community noise for several reasons:
1. Compliance of noise produced by facilities operating in regions with local ordinances,
2. Determination of acceptable noise levels and noise characteristics for new equipment,
3. Evaluation of site suitability for a new facility,
4. Resolution of complaints from neighbors.
The course material is structured to enable health, safety, and environment professionals to meet the unique survey needs described above. The instructors will also cover the various types of community noise regulation, factors and conditions affecting sound propagation outdoors, instrumentation and survey procedures for measuring noise, and how to interpret the data.
Upon completion of this training course, the attendees should be able to understand and apply the community noise concepts to:
Describe the various types of Federal, State, and local noise regulations;
Conduct a community noise survey and determine compliance based on the criteria specified in all applicable regulations;
Identify factors that affect outdoor sound propagation; and
Predict the impact new equipment, new facilities, or plant expansion projects will have on the existing ambient noise environment and regulatory compliance.
Introduction and Course Objectives • Concepts in Community Noise: Federal, State, and Local Regulations • Factors and Conditions Affecting Sound Propagation Outdoors • Workshop 1 - Predicting Sound Levels at Property Line Locations • Measuring Community Noise: Instrumentation and Survey Protocol • Workshop 2 - Conducting a Community Noise Survey • Interpreting Survey Data and Determining Regulatory Compliance • Course Conclusion & Wrap Up
