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
  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: M3, 8-core CPU / 10-core GPU, 16GB unified memory, 1TB storage.
