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 .

K v is the statistical adder for computing upper-limit of A-weighted sound power level.

L p A,m is the mean A-weighted sound pressure level measured at operator position (rounded to the nearest 1 dB).

L W A,m is the mean A-weighted sound power level, rounded to the nearest 0.1 B.
