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.
