ac vifte. hvor høy Db?

[Gjest Slettes-xwByZdFZ]

Jeg lurer på å kjøpe et par av Disse viftene... men det eneste som står om lyd, er at den er på 0.8 i lydskalaen. jeg lurer på hva sånn ca. dette tilsvarer i desibel?

Noise Level

All measurements are taken using full fan speed.

The noise level is measured in Sone (loudness) instead of dB (sound pressure).

The loudness depends upon ears response curves and tells you exactly, how bothering a certain noise is. Sone takes the frequency and bandwidth of a sound into account.

A doubling of the number of Sones sounds to the human ear like a doubling of the loudness.

The comparison of products from different manufacturers is basically impossible, since all manufacturers measure in different ways. Even a rough translation from Sone to dB doesn't help. A 15dB cooler can be louder than a 1 Sone cooler from another manufacturer.

 

Nevertheless with the Sone data you can compare our coolers between each other and get a quite precise idea how annoying the product will be.

1 Sone: nearly inaudible in a computer case

2 Sones: clearly audible

3 Sones and more: disturbing

 

Noise Level

The noise level is measured in Sone (loudness) instead of dB (sound intensity).

The loudness depends upon ears response curves and tells you exactly, how bothering a certain noise is.

er usikker, men jeg har den s939 kjøleløsningen som srtic cooling bruker den vifta på, og den er veldig stille... ikke over 15db
