- 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.
- Configuration tested: 2.3GHz dual-core Intel Core i5 processor, 8GB memory, 1TB hard drive, Intel Iris Plus Graphics 640.
