HVAC-System Acoustics

August 2008
Heating/Piping/Air Conditioning Engineering;Aug2008, Vol. 80 Issue 8, p16
The article provides methods of reducing noise associated with mechanical systems in commercial buildings. It also offers an overview of acoustics concerning HVAC-system design. To reduce noise, it is advised to select the equipment with the lowest sound-pressure levels at operating conditions, locate air-handling equipment as far from sound-sensitive areas as possible, and reduce air velocity by occupying larger ductwork, particularly near terminal outlets.
