5.10 Acoustics
The acoustical design of the PowerEdge T610 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, hums, etc. One of the sound
quality metrics in the Dell specification is prominence ratio of a tone as shown in Table 7 and Table
8.

The acoustical specification for the T610 is Category III-C.
Definitions
Idle: Reference ISO7779 (1999) definition 3.1.7; system is running in its OS but no other specific activity.
Stressed Processor: An operating mode per ISO7779 (1999) definition 3.1.6. The software SPECPower_ssj2008 is
utilized to stress the processors. SPECPower is set to 50% loading.
LwA – UL: The upper limit sound power level (LwA) calculated per section 4.4.2 of ISO 9296 (1988) and measured
in accordance to ISO7779 (1999).
LpA: Average bystander A-Weighted sound pressure level. The system is placed in a rack with its bottom at 25
cm from the floor. The acoustic transducers are at the four bystander positions, ref ISO7779 (1999) Section
8.6.2.
Prominent tone: Criteria of D.5 and D.8 of ECMA-74 9th ed. (2005) are followed to determine if discrete tones
are prominent. The system is placed in a rack with its bottom at 75 cm from the floor. The acoustic transducer
is at front bystander position, ref ISO7779 (1999) Section 8.6.2.
