PowerEdge R510 Technical Guide 39
5.6 Acoustics
The acoustical design of the PowerEdge R510 reflects the following:
Adherence to Dell’s high sound quality standards. Sound quality is different from sound
power level and sound pressure level in that it describes how humans respond to
annoyances in sound, like whistles, hums, etc. One of the sound quality metrics in the Dell
specification is prominence ratio of a tone, and this is listed in the table below.
Noise ramp and descent at bootup. Fan speeds, hence noise levels, ramp during the boot
process to add a layer of protection for component cooling in the case that the system does
not boot properly.
Noise levels vs. configurations. Hardware configurations affect system noise levels. Dell’s
thermal control provides for optimized cooling with varying hardware configurations, as
shown in the tables below.
