(1) Typical configuration means the system is populated with projected average quantity, type,
capacity, speed, etc., of components, as shown in the table below
(2) LwA – UL is 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).
(3) LpA is the average bystander A-Weighted sound pressure level. The system is placed in a rack
with its bottom at 25 cm from the floor, and four acoustical transducers are at bystander
positions, ref ISO7779 (1999) Section 8.6.2.
(4) 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 acoustical transducer is at front bystander position, ref ISO7779 (1999) Section 8.6.2.
