Radiated noise produces Lw in the various octavebands and total LwA. Radiated noise is calculated by taking thenoise value from the supply air table and deducting the totalvalue from the correction factor table.Correction factor for LwHz 63 125 250 500 1000 2000 4000 8000 Total LwASupply air 3 2 -2 -5 -5 -6 -13 -29Extract air 18 14 1 -12 -14 -28 -37 -43Radiated -47 -42 -40 -43 -44 -45 -49 -57 -38,7Supply air data is measured in accordance with ISO 5136, the inductmethod. Radiated noise is measured in accordance with ISO9614-2.
