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 speed of the fan.
Average sound-pressure levels:
At operator position:
Idle: 33 dBA
Operating: 35 dBA
At bystander position - 1 meter:
Idle: 30 dBA
Operating: 32 dBA
Declared (upper limit) sound-power levels:
Idle: 4. bels
Operating: 4.5 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.
