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 the noise level, the maximum value of the measured sound pressure level is used. Read
the value at each frequency level (on horizontal axis, center of the sound pressure band) from 63 Hz
to 8000 Hz, and select the corresponding maximum value indicated on the vertical axis.
