Acoustic Data
Sound Power Levels
ART COOL GALLERY
• 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 level will vary depending on a range of factors such as con-
struction (acoustic absorption coefficient) of particular area in which
the equipment is installed.
• Reference acoustic intensity: 0dB = 10E-6μW/m
