Acoustic Performance
Declared noise emission values following ECMA-109
| Sound Power Level L W A,m (B) | Sound Pressure Level Operator Position Lp A,m (dB) |
---|
Idle | 2.0 (K V = 0.3) | 12 |
---|
Wireless web | 2.0 (K V = 0.3) | 12 |
---|
Hard drive seek | 2.1 (K V = 0.3) | 13 |
---|
- L W A,m is the mean A-weighted sound power level, rounded to the nearest 0.1 B.
- Lp A,m is the mean A-weighted sound pressure level measured at the operator position (rounded to the nearest 1 dB).
- 1 B (bel) = 10 dB (decibel)
- K v is the statistical adder for computing the upper limit of the 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: 3.0GHz 6-core Intel Core i5 processor, 8GB memory, 1TB Fusion Drive, Radeon Pro 560X Graphics.
