Nazdar,
v.sv napisal (mail mal 601 bajtov):

> Hlucnost, dB neni linearni, ale tusim logaritmicka, takze 40 neni
> 1/4 ze 160 !!

Ale ved ano, bol tam smajl na konci vety. Db sa meraju logaritmicky.
Takze ak mam zvuk s 10 dB a 20 dB tak ten druhy je 10 krat silnejsi,
ale ked mam 30 dB tak ten je uz 100 krat silnejsi ako 10 dB, atd.

> A stejne tak 2 zdroje zvuku 30dB (treba vetracky v PC) nedavaji dohromady
> 60dB, nescita se to !!

To je uplne jasne.

>>Takze ten zvlhcovac (40dB) je 1/4 hlucnosti startu raketoplanu ;)


S pozdravom,
