Notes:
- Data is valid at nominal operation condition
- Reference accoustic pressure OdB = 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.
