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)
Idle2.1 (K V = 0.3)13
Wireless web2.1 (K V = 0.3)13
  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. Configuration tested: 3.2GHz 8-core Intel Xeon W processor, 32GB memory, 1TB storage, Radeon Pro Vega 56 Graphics. 

  1. 1TB = 1 trillion bytes; actual formatted capacity less.
  2. Weight varies by configuration and manufacturing process.
  3. iMovie, GarageBand, Pages, Numbers, and Keynote are available on the Mac App Store. Downloading apps requires an Apple ID and a device that is compatible with the OS version required for each app.
  4. PVC-free AC power cord available in all regions except India and South Korea.
