<Hlucnost, dB neni linearni, ale tusim logaritmicka, takze 40 neni 1/4 ze
160
<!! A stejne tak 2 zdroje zvuku 30dB (treba vetracky v PC) nedavaji
dohromady
<60dB, nescita se to !!

Dva vetracky (plati, ze 3dB jsou dvojnasobny hluk)
30dB+30dB=33dB
40dB+40dB=43dB

Ventilator versus raketoplan:
40dB=E+4
160dB=E+16
rozdíl E+12 je bilionkrat !
