iMac (24-inch, M1, 2021) - 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 1.7 (K V = 0.3) 7
Wireless web 1.7 (K V = 0.3) 7
  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.
