The Declared Noise Emission in accordance with ISO 9296 for the Dell Optiplex 980 MT is as follows5:
(all values LWAd expressed in bels6; 1 bel=10 decibels, re 10-12 Watts; all values LpA expressed in decibels3, re 2x10-5 Pa)
Sound Power
Sound Pressure at Operator Position
5 All tests are conducted according to ISO 7779 and declared according to ISO 9296 except 90% CPU. For this mode, the system
CPU was stressed at 90% utilization with no other peripheral device actively seeking. This test mode is not specified in ISO 7779, but
was measured using the same microphone distances and measurement techniques defined for the other reported operating modes.
6 Declared Sound Power rounded to the nearest tenth of a bel per ISO 9296 section 4.4.2
3 Declared Sound Pressure rounded to the nearest whole decibel per ISO 9296 section 4.4.4
