1. 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 manufacturer has no way
of knowing the details of each system. This constitutes an exception to any specification or guarantee requiring a dBA value of sound data
in any other form than sound power level ratings.
