REMARKS: 1. Value obtained in the actual place
where the unit is installed may be
slightly higher than the values shown in
this graph because of the conditions of
operation, the structure of the building,
the background noise and other factors.
2. The test results were obtained from an
anechoic room.
NOTE To evaluate “Noise level” the maximum number
of the measured OCTAVE BAND SOUND
PRESSURE LEVEL is used. Read the number
on each BAND CENTER FREQUENCIES
(horizontal axis) ranging from 63 Hz to 8000 Hz
and select the maximum value (vertical axis)
among them.
