Acoustic Performance

Declared noise emission values in accordance with ECMA-109

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 25 popular websites.

7. Configurations tested: a) Apple M1 chip, 8-core CPU/8-core GPU, 8GB memory, 512GB storage, 4-ports b) Apple M1 chip, 8-core CPU/7-core GPU, 8GB memory, 256GB storage, 2-ports.
