Overall
Note
• Sound measured at 1.5m away from the center of the unit.
• Data is valid at free field condition.
• Data is valid at nominal operation condition.
• Reference accoustic pressure 0dB=20
μ
Pa.
• Sound level will vary depending on a range of factors such
as the construction(acoustic absorption coefficient) of
particular room in which the equipment is installed.
• The operating conditions are assumed to be standard.
