AHU Casing Correction    1/1, 1/3

Strutt|Input Data|Empirical|AHU Casing Correction inserts octave band adjustments into the active row of the worksheet.

The adjustments are for determining the sound power radiated by AHU housings.

These octave band values should be subtracted from the calculated sound power level.

Octave band adjustments have been provided by the air handling systems manufacturer G J Walker, as follows:

63 Hz 125 Hz 250 Hz 500 Hz 1 kHz 2 kHz 4 kHz 8 kHz
-11 dB -11 dB -14 dB -12 dB -19 dB -26 dB -33 dB -35 dB
