NOTES:
1. Outdoor sound data is measure in accordance with
AHRI.
2. Measurements are expressed in terms of sound power.
Do not compare these values to sound pressure values
because sound pressure depends on specific environ-
mental factors which normally do not match individual
applications. Sound power values are independent of
the environment and therefore more accurate.
3. A---weighted sound ratings filter out very high and very
low frequencies, to better approximate the response of
“average” human ear. A---weighted measurements for
Bryant units are taken in accordance with AHRI.
