Inaudible Flow Rates - Side Square Diffusers

The following airflows give a noise level of 17dB.  Installers often use 25dB as the level of inaudible noise.  We use a lower figure to allow for other fixings such as dampers and other constrictions upstream of the diffuser and also to allow for some margin of error.
