LEGEND	NOTES:
dB --- Decibel	1. Outdoor sound data is measure in accordance with
	AHRI.

Use of the AHRI Certified TM Mark indicates a manufacturer’s participation in the program For verification of certification for individual products, go to www.ahridirectory.org.

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.
