Noise Level Data
VIA have been at the forefront of the quiet computing initiative. The VIA VT310-DP Series has been
designed to be totally non-obtrusive with noise levels equivalent to a person whispering. With noise
levels measuring at the totally silent 0dBA, a new wave of system design innovation and exciting
opportunities are being created in an almost limitless number of emerging new market segments -
ranging from fanless thin clients, flat panel small form factor desktop replacement systems, LCD PCs,
high density servers and a host of other space and power saving systems.
Common Sounds dBA Level
Threshold of hearing 0 dBA
VIA VT310-DP 0 dBA
Normal breathing 10 dBA
Whispering at 1 meter 20 dBA
Conventional PC 35 – 50 dBA
Rainfall 50 dBA
Normal speech 60 dBA
The dBA scale is logarithmic, i.e. 10 dBA represents a doubling in volume. dBA values are measured at a
distance of one meter.
