NOTE:
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
for reference only. Calculation of dBA values cover matters of system design and the fan manufacturer has no way of knowing the details of each sys-
tem. This constitutes an exception to any specification or guarantee requiring a dBA value or sound data in any other form than sound power level rat-
ings.
