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 |
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 25 popular websites.
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.
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
1GB = 1 billion bytes and 1TB = 1 trillion bytes; actual formatted capacity less.
Weight varies by configuration and manufacturing process.
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.
