Declared noise emission values in accordance with ECMA-109
|Sound Power Level
L W A,m (B)
|Sound Pressure Level
L p A,m (dB)
|Idle||2.25 (K v = 0.25)||15.5|
|Wireless web||2.25 (K v = 0.25)||15.5|
|Hard drive seek||2.25 (K v = 0.25)||15.5|
- L W A,m is the mean A-weighted sound power level, rounded to the nearest 0.05 B.
- L p A,m is the mean A-weighted sound pressure level measured at the operator position (rounded to the nearest 0.5 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.
- Configuration tested: 3.3GHz quad-core Intel Core i5 processor, 8GB memory, 2TB Fusion Drive, AMD Radeon R9 M395 graphics.
- 1GB = 1 billion bytes and 1TB = 1 trillion bytes; actual formatted capacity less.
- Weight varies by configuration and manufacturing process.
- Siri may not be available in all languages or in all areas, and features may vary by area.
- 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.
