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 an exception to any specification or guarantee
requiring a dBA value of sound data in any other form than sound power level ratings.
