Esempi
The drives are rated at under 2.5 bels of acoustic power, the same level of acoustic noise produced by Seagate's PC drives.
The present invention is a computer chassis assembly that can adequately cool an electronic system which generates 450 watts of heat, without emitting cooling fan noise above 5 bels of sound power.
Select a heat pump with an outdoor sound rating of 7.6 bels or lower.
They are also exceptionally quiet, emitting just 2.1 bels of noise at idle.
As for the acoustic characteristics of the drive it generates 2.4 bels of noise in the idle mode.
