NOTES:

 

 

 

 

dB --- Decibel

 

 

 

 

1. Outdoor sound data is measure in accordance with ARI stand-

ard 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 environmental factors which do not match individual applications. Sound power values are inde- pendent 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 an “aver- age” human ear. A---weighted measurements for Bryant units are taken in accordance with 270---95.
