- 6.4 bel for typical system configuration (3 hard disk drives installed) Sound pressure, idling - 45 dBA for open bay system (no hard disk drives installed) - 45 dBA for typical system configuration (3 hard disk drives installed) Sound pressure, operating - 45 dBA for open bay system (no hard disk drives installed) - 46 dBA for typical system configuration (3 hard disk drives installed) These levels are measured in controlled acoustical environments according to ISO 7779, and are reported in accordance with ISO 9296. 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 values stated because of room reflections and other nearby noise.
