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