LEGEND	NOTES:
dB --- Decibel	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.
