Dell OptiPlex 7420 - Acoustic Noise Emission Information for Computers Shipped with a High Performance Processor

The Declared Noise Emission in accordance with ISO 9296 is as follows (all values L
WA,m
and K
V
expressed in bels; 1 bel=10
decibels, re 10-12 Watts.
The Declared A-weighted Sound Pressure Level in decibels (re 2x10-5 Pa), are measured in accordance with ISO 7779 7.6.1,
7.6.2, and C.15.2 and declared in accordance with ISO 9296 and rounded to nearest tenth of a bel per ISO 9296 section 4.4.2
