• Measurements taken with no attenuation and units operating at full
load normal operating condition.
• 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.
• Sound power levels are measured in dB(A)±3.
• Tested in anechoic chamber per ISO Standard 3745.
