14. SOUND DATA
Sound power
Airedale determines sound power values
in agreement with the 9614 Standard,
in compliance with that requested by
Eurovent certification.
Sound Pressure
Sound pressure measured in free
field conditions with reflective surface
(directivity factor Q=2) at 10mt distance
from external surface of unit, in
compliance with ISO 3744 regulations.
