L
WA
-UL is the upper limit sound power levels (L
WA
) calculated per section 4.4.1 of ISO 9296 (1988) and measured in
accordance to ISO 7779 (2010).
2
L
pA
is the average A-weighted sound pressure level from the four bystander positions calculated per section 4.3 of
ISO9296 (1988) and measured in accordance with ISO 7779 (2010). The system is placed in a half rack enclosure (base of
system is 25 cm above reflective floor).
3
Prominent tone: Criteria of D.6 and D.11 of ECMA-74 11th ed. (2010) are followed to determine if discrete tones are
prominent. The system is placed in a half rack enclosure (base of system is 75 cm above reflective floor) and acoustic
transducer is at front bystander position, ref ISO7779 (2010 Section 8.6.2).
4
Idle: Reference ISO 7779 (2010) definition 3.1.7; system is running in its operating system but no other specific activity.
5
Stressed processor: An operating mode per ISO 7779 (2010) definition 3.1.6. The software SPECPower at 50% loading is
activated to stress the processors.
