NOTES:
1. Outdoor sound data is measured in accordance with
AHRI standard 270---95.
2. Measurements are expressed in terms of sound power.
Do not compare these values to sound pressure values
because sound pressure accounts for specific environ-
mental factors which do not match individual applica-
tions. Sound power values are independent of the envir-
onment and therefore more accurate.
3. A ---weighted sound ratings filter out very high and very
low frequencies, to better approximate the response of
an “average” human ear. A ---weighted measurements for
Carrier units are taken in accordance with 270---95.
