L W A,m is the mean A-weighted sound power level, rounded to the nearest 0.1 B.
-
L p A,m is the mean A-weighted sound pressure level measured at operator position (rounded to the nearest 1 dB).
-
1 B (bel) = 10 dB (decibel)
-
K v is the statistical adder for computing upper-limit of A-weighted sound power level.
-
The quantity, L W A,c (formerly called L W Ad) may be computed from the sum of L W A,m and K v .
-
The Wireless web test browses 25 popular websites.
