Dell PowerEdge R750XA is a rack-mount server whose acoustical out ranges from that appropriate for an office to that of data centers. Acoustical performance is provided in terms of one configuration: configuration details are provided in Table 27 for GPU configuration; acoustical performance data for this configuration is in Table 28. Because the GPU dominates thermal thus acoustical output, few options exist to further reduce the acoustical output. If ambient temperature or other components dominate, then Tips for acoustically sensitive environments may be helpful.

LwA,m: The declared mean A-weighted sound power level (LwA) is calculated per section 5.2 of ISO 9296 with data collected using the methods described in ISO 7779 (2010). Engineering data presented here may not be fully compliant with ISO 7779 declaration requirements.
LpA,m: The declared mean A-weighted emission sound pressure level is at the bystander position per section 5.3 of ISO 9296 and measured using methods described in ISO 7779. The system is placed in a 24U rack enclosure, 25cm above a reflective floor. Engineering data presented here may not be fully compliant with ISO 7779 declaration requirements.
Prominent discrete tones: Criteria of Annex D of ECMA-74 & Prominence Ratio method of ECMA-418 are followed to determine if discrete tones are prominent and to report them, if so.
Idle mode: Idle mode is the steady-state condition in which the server is energized but not operating any intended function.
Operating mode: Operating mode is represented by the maximum of the steady state acoustical output at 50% of CPU TDP or active storage drives for the respective sections of Annex C of ECMA-74.
