pressure depends on specific environmental factors which nor-
mally 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 fre-
quencies, to better approximate the response of "average" human
ear. A-weighted measurements for Bryant units are taken in
accordance with AHRI.
