Overall
Notes:
- Sound measured at 1m away with 1.5m height.
- Data is valid at free field condition.
- Data is valid at nominal operation condition.
- Reference acoustic pressure acoustic 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.
