MacBook Pro (14-inch, Nov 2023) - Acoustic Performance
Acoustic Performance
Declared noise emission values in accordance with ECMA-109
| Sound Power Level L W A,m (B) | Sound Pressure Level Operator Position L p A,m (dB) | |
|---|---|---|
| Idle | 1.3 (K V = 0.3) | 3 |
| Wireless web | 1.3 (K V = 0.3) | 4 |
- 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 6 tabs with a mix of content including media.
- Configuration tested: M3, 8-core CPU / 10-core GPU, 16GB unified memory, 1TB storage.
