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.
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.
