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.
