Acoustic Performance 

Declared noise emission values in accordance with ECMA-109 

  Sound Power Level

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.

  1. Magic Keyboard with Touch ID is included with the 24‑inch iMac systems with Apple M1 chip and 8‑core GPU and is available as an option on systems with 7‑core GPU
  2. 1GB = 1 billion bytes and 1TB = 1 trillion bytes; actual formatted capacity less.
  3. Weight varies by configuration and manufacturing process.
  4. 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.
  5. Data accurate as of product launch.
  6. ENERGY STAR and the ENERGY STAR mark are registered trademarks owned by the U.S. Environmental Protection Agency.
  7. Apple defines its restrictions on harmful substances, including definitions for what Apple considers to be “free of,” in the Apple Regulated Substances Specification. Every Apple product is free of PVC and phthalates with the exception of AC power cords in India, Thailand (for two-prong AC power cords), and South Korea, where we continue to seek government approval for our PVC and phthalates replacement.
