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

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

  3. 1 B (bel) = 10 dB (decibel).

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

  5. 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 .

  6. The wireless web test browses 6 tabs with a mix of content including media.

  7. Configuration tested: M4 Max, 14-core CPU / 32-core GPU, 36GB unified memory, 2TB storage.
