Acoustic Performance

Declared noise emission values by ECMA-109

1. L _W A,m is the mean A-weighted sound power level, rounded to the nearest 0.1 B.
2. _Lp A,m is the mean A-weighted sound pressure level measured at the 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 25 popular websites.
7. Configuration tested: 3.7GHz 6-core Intel Core i5 processor, 8GB memory, 2TB Fusion Drive, Radeon Pro 580X Graphics.
