Acoustical noise-emission values
Note: In this computer, fan speed is controlled by
temperature, configuration, and software. Actual
noise-emission values might be different from the stated
values depending on the number of fans and the speed
of the fans.
Average sound-pressure levels:
At operator position (0.5 meters):
Idle: 29 dBA
Operating: 34 dBA
At bystander position - 1 meter (3.3 ft):
Idle: 26 dBA
Operating: 29 dBA
Declared (upper limit) sound-power levels:
Idle: 4.0 bels
Operating: 4.3 bels
Note: These levels were measured in controlled
acoustical environments according to the procedures
specified by the American National Standards Institute
(ANSI) S12.10 and ISO 7779 and are reported in
accordance with ISO 9296. Actual sound-pressure levels
in a given location might exceed the average values
stated because of room reflections and other nearby noise
sources. The declared sound-power levels indicate an
upper limit, below which a large number of computers
will operate.
