Overview

Sound attenuators (silencers) are used in HVAC systems to help absorb noise that is generated by fans or other air moving equipment. Attenuators can also be used to prevent cross-over noise between rooms, such as conference rooms or toilet rooms. Manufacturers of attenuators such as AeroSonics offer a variety of attenuator types and models uniquely designed for a multitude of applications.

In this course the student will learn fundamentals of attenuator design and selection, including the various types of attenuator styles and specific models as manufactured by AeroSonics. Models, styles, performance, specification and installation considerations related to sound attenuators, louvers and panels are covered in this course.

The course includes an introductory section on attenuator fundamentals, followed by material contained in the AeroSonics engineering binder* that is provided here in PDF format.

State Board Acceptance

This course can be used by professional engineers to fulfill PDH requirements mandated by state and provincial licensing boards. Decatur Professional Development is an approved provider of continuing education in all states that pre-approve course providers. In all other states that mandate continuing education for engineers, it is the individual engineer's responsibility to determine the suitability of activities for PDH credit. The state boards typically accept online* courses that cover technical, managerial** or ethical content and which are relevant to the practice of engineering. The course must have a clear purpose or objective with a content that will maintain, improve or expand the skills and knowledge of the licensee's field of practice. For questions about your mandatory PDH requirements, visit the website of your state licensing board.

*Online courses are accepted by all state licensing boards that mandate continuing education. Other than New York (which limits online courses to 18 PDH) and Iowa (which limits online courses to 6 PDH), there are no limits placed by other states on the number of hours that can be earned through online continuing education. Consult with your state licensing board if you have any questions about the acceptability of online courses.

**The New York State Board of Engineers does not accept general office management courses, but will accept project management courses that are offered by an approved provider and that are technical in nature and contribute to the engineer's professional practice.

Please Note: Continuing Education credits for this course are awarded as PDH (Professional Development Hour Credits).
