Acoustical noise emission values
For open bay (0 drives installed) and typical
system configurations (eight hard disk drives
installed):
v Sound power (idling):
– 5.9 bel (open bay)
– 6.1 bel (typical)
v Sound power (operating):
– 5.9 bel (open bay)
– 6.2 bel (typical)
v Sound pressure (idling):
– 44 dBA (open bay)
– 46 dBA (typical)
v Sound pressure (operating):
– 44 dBA (open bay)
– 47 dBA (typical)
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 1-meter values stated because of
room reflections and other nearby noise.
