Topic:  Sound Advice 

Good acoustical design plays a major role in creating comfortable and productive indoor environments. Air terminal units and air outlets are located in close proximity to occupants, so they tend to have the greatest impact on room sound levels. The proper sizing and selection of these products is critical to achieving the desired acoustical environment. Manufacturers publish sound performance ratings but they are of little value without a proper understanding of what they mean and where they come from. In order to properly specify system components, a basic knowledge of acoustical terminology, ratings and criteria is required.


Attending this session will improve your knowledge and understanding of HVAC acoustics.


  •      You will learn about the various industry standards used for testing and rating the acoustical performance of terminal units and air devices.
  •      You will learn how to apply manufacturers’ acoustical data in order to achieve design goals.
  •      You’ll learn the differences between noise criteria and the importance of sound quality in creating optimal acoustical environments.
  •      You will learn the best techniques for specifying acoustical performance.
  •      You will learn how to select and install terminal units and air devices for improved acoustical performance.
