• Data is valid at free field condition
• Data is valid at nominal operating condition
• 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(ISO conditions)
