• Data is valid under diffuse field conditions.
• Data is valid under nominal operating conditions.
• Sound level may be increased in static pressure mode or if air
guide is used.
• Sound power level is measured using rated conditions, and tested
in a reverberation room per ISO 3741 standards.
• Sound level will vary depending on a range of factors such as
construction (acoustic absorption coefficient) of particular area in
which the equipment is installed.
