L
is the average bystander position A-weighted sound pressure level calculated per section 4.3 of ISO 9296 (1988) and
pA
measured in accordance with ISO 7779 (2010). The system is placed within a rack enclosure (base of system is 75 cm
above floor).

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 inside rack in 75 cm height and acoustic transducer, binaural head, is at front bystander
position, ref ISO 7779 (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
Stress: An operating mode per ISO 7779 (2010) definition 3.1.6. The software SPECPower at 50% is activated to stress the
processors and DIMM.
