NOTE
To evaluate the noise level, the maximum value of the
NC-40
measured sound pressure level is used. Read the value
NC-30 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.

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.
