9.2 Sound Power Levels
Notes:
• Data is valid at diffuse field condition
• Data is valid at nominal operating condition
• Sound level can be increased in static pressure mode or
used air guide.
• Sound power level is measured on the rated
condition(external static pressure of standard mode) in
the reverberation rooms.
•
Sound level will vary depending on a range of factors such
as the construction (acoustic absorption coefficient) of par-
ticular room in which the equipment in installed.
•
Reference acoustic intensity 0dB = 10E-6μW/m
