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 particular
room in which the equipment in installed.
• Reference acoustic intensity 0dB = 10E-6μW/m
