Sound Pressure Level

Notes:

-Sound measured at 1m away from the center of the unit.

-Data is valid at free field condition.

-Data is valid at nominal operation condition.

-Reference accoustic pressure 0dB=20∝Pa.

-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(KS conditions).
