Abstract
Over the last several decades, ASHRAE has sponsored several research efforts in an effort to better understand noise propagation in heating, ventilation, and air-conditioning (HVAC) ductwork. Much of this work is the basis for the duct insertion loss and breakout noise information in the ASHRAE Handbook—HVAC Applications. Though this information is widely used in the building industry, the Handbook provides little information about the basisfor the equations and potential limitations. This paper reviews the past work supported by ASHRAE, provides context for the information in the ASHRAE Handbook, and examines shortcomings of which designers should be aware. In addition, more recent research efforts are reviewed, including a recently completed measurement campaign in ASHRAE RP-1408 (Reynolds et al. 2018) and a finite element simulation approach for simulation of HVAC components. ASHRAE Handbook results are compared to the more recent measurement and thefinite element results so that the limitations of the handbook are better understood. Future research directions are recommended at the conclusion of the paper.
