Note
‐ Sound measured at 1 m away from the unit.
‐ Data is valid at free field condition.
‐ Data is valid at nominal operation condition.
‐ Reference acoustic pressure 0dB=20μPa.
‐ 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.
‐ Sound pressure level is measured on the rated condition in the anechoic rooms by ISO 3745 standard.
‐ Sound level is measured in an anechoic room and may be different according to the test condition or equipment.
