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.
