NC-65
• Measurements are taken 3.3 ft away from the front of the unit.
• Sound pressure levels are measured in dB(A) with a tolerance of
±1.
• Data is valid at nominal operation conditions. Operating conditions
are assumed to be standard.
• Reference acoustic pressure 0dB=20μPa
• Sound pressure levels are tested in an anechoic chamber under
ISO Standard 3745, and may be different according to the test
condition or equipment.
• Sound level will vary depending on a range of factors including the
construction (acoustic absorption coefficient) of a particular room in
which the unit was installed.
