Sound power, operating - 6.2 bel for open bay system (no hard disk drives installed) - 6.3 bel for typical system configuration (1 hard disk drive installed) Sound pressure, idling - 47 dBA for open bay system (no hard disk drives installed) - 48 dBA for typical system configuration (1 hard disk drive installed) Sound pressure, operating - 47 dBA for open bay system (no hard disk drives installed) - 48 dBA for typical system configuration (1 hard disk drive installed) These levels are measured in controlled acoustical environments according to ISO 7779 (EMCA-74), and are reported in accordance with ISO 9296 (EMCA-109). The declared sound power levels indicate an upper limit, below which a large portion of machines operate. Sound pressure levels in your location might exceed the average 1-meter values stated because of room reflections and other nearby noise.
