NOTES:
1. Outdoor sound data is measure in accordance with
AHRI standard 270---2008.
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 stand-
ard 270---2008.
