These values have been accessed using a model of sound propagation from a point source into the hemispheric\free field. The
dBA values provided are to be used for reference only. Calculation of dBA values cover matters of system design and the fan
manufacture has no way of knowing the details of each system. This constitutes and expectation to any specification or guarantee
requiring a dBA value or sound data in any other form than sound power level ratings.

For units with VFD and electric or gas heat, the
speed of the indoor blower motor continues to
be controlled by duct static pressure via the
VAV control board.
