Notes:
- Sound measured at 3.3ft away from the unit.
- Data is valid at free field condition.
- Data is valid at nominal operation condition.
- Reference accoustic 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.
