Alamo ASHRAE,

Working in the HVAC industry we routinely consider things like loads, pressure drops, flow rates, amperage, controls, etc. Those items are usually very tangible and quantifiable. There are some other areas that we need to consider that, in my mind, are not as apparent, such as acoustics and vibration. I remember when I was first presented the challenge of predicting the acoustic performance of one of my designs. I remember being handed a nonograph with some ductwork acoustic properties however I really didn’t capture exactly the science in what I was attempting to evaluate. As I gained experience, I came to realize how important the accuracy of noise and vibration analysis is during design. After working many years in construction, mitigating unwanted noise and vibration is very difficult and costly in the filed once the equipment and systems are in place.

The subject on this month’s presentation is “Acoustic Basics for HVAC&R Designers”.

Our presenter this month will be Mr. Mark Fly, P.E.. He is an ASHRAE Fellow, with over 38 years of experience as a Researcher, Consulting Engineer, Contractor, and Manufacturer in the HVAC Industry. He holds a Bachelor of Science in Physics from Missouri State University, is active on ASHRAE TC 2.6, 5.1, 9.0, 9.12, a member of ASHRAE Certification Committee serving as Chair of the new Certified HVAC Designer development committee, and a past Director at Large on the ASHRAE Board of Directors. At AHRI he has served on the Board of Directors, as Section Chair for Unitary Large Equipment, Section Chair for Air to Air Energy Recovery, as a member of the Technical on Sound and is currently member of the Systems Steering Committee.

His presentation will expose participants to:

  • The fundamentals of acoustics
  • How sound is measured and reported
  • Levels that are sound spectrums appropriate for different environments and activities
  • Different sound measurements and ratings
  • How to apply different types of criteria rating systems to achieve acceptable noise for the people living and working in the space

Please join us on Tuesday, Nov 19, 2019 from 11:30-1:00 PM at Alamo Drafthouse Cinema - Park North. Also please don’t forget to register for the Alamo ASHRAE Skeet Shoot on Nov 15, 2019 at the San Antonio Gun Club.

Additional information regarding Mr. Fly and the presentation details can be found on the Alamo ASHRAE website.

Thanks,

Frank L Painter, P.E.
