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 1 2 -1 -7 -11 -18 -31Extract air 10 8 5 -2 -11 -19 -30 -48Radiated -55 -43 -35 -36 -33 -31 -40 -50 -27,1Supply air data is measured in accordance with ISO 5136, the inductmethod. Radiated noise is measured in accordance with ISO9614-2. Bruel & Kjær measuring equipment, type 2260.Blue curves: Air capacity at various capacitysettings in Volt.Green curves: Supply air fan power consumptionat various capacity settings.Red curves: Sound power level LwA, cf.correction table.Light blue correction axe: Pressure increaseusing an EU-5 filter.Light green correction axe: Pressure increaseusing water battery.21
