Acoustics
The acoustical design of the PowerEdge M710HD reflects 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 or hums. Definitions for
acoustical performance data are as follows:
•
Idle:
Reference ISO7779 (1999) definition 3.1.7; system is running in its OS but no other
specific activity.
•
LwA–UL:
The upper limit sound power level (LwA) calculated per section 4.4.2 of ISO 9296
(1988) and measured in accordance to ISO 7779 (1999).
Table 4 shows the acoustical performance for a typical configuration of the M1000e chassis with eight
PowerEdge M710HD blade servers installed. Acoustical performance varies with hardware
configurations.
