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.
3. The layout of the testing condition is shown at right.
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.
