Consider Various Pressure Control Methods in a VAV System

All diffusers become noisier with higher pressures at their inlet and this is true for VAV diffusers.  Pressure is often reduced by the use of a balancing damper or terminal unit, but VAV diffusers are unique as they have a built in VAV damper that can close down to a minimum flow.

Inlet Effects 

ASHRAE Standard 70 guidelines are in place so that ideal conditions are present during GRD testing
and to ensure the testing is repeatable. It is important to note that the performance
published in the Price catalog is based on these ideal conditions outlined in ASHRAE 70 and that
any field modifications can affect the performance of the outlet. There are five common field conditions and their influence on the air pattern of a given diffuser:
