7.1 Sound Pressure Level
̰
Overall
Note
1.Sound measured at some distance away from the center of
the unit.
2.Data is valid at free field condition.
3.Reference accoustic pressure 0dB = 20μPa.
4.Data is valid at nominal operation condition.
Refer to the Model Specifications for nominal
conditions(Power source and Ambient temperature, etc)
5.Sound levels can be increased in accordance with
installation and operating conditions. (Static pressure mode,
used air guide, Room target temperature setting, etc)
6.Sound level will vary depending on a range of factors such
as the construction(acoustic absorption coefficient) of
particular room in which the equipment in installed.
7.Sound pressure level is measured on the rated condition in
the anechoic rooms. (LG Internal Standard)
Therefore, these values can be increased owing to ambient
conditions during operation.
