dB(A) @ 3m:
Inlet Side =

All values are positive unless shown otherwise.
* Add the In-Duct Spectrum Corrections to the appropriate dB(A) level shown on
the graph to obtain the In-Duct Sound Power Levels. Note: there are levels for
both the Inlet and Outlet Sides of the units.
The figures in the box are correction factors to apply to the dB(A) figure for the Inlet or Outlet Side.
