Impossible question, favor asking "One to apologize is same to just how manyOranges" Simply set :

Decibels the the unit that volume, just how loud things go

hertz is how fast things change, the frequency (number ofchanges every second). As soon as you talk about music, differentfrequencies deserve to have a various volume. Friend can also measure thevolume in frequency ranges - look up : paragraphic equalizer forthe principle.

+db= 10*log(p2/p1)

+db= 10*log(2watts/1watt)

+db= 10*log(2)

+db= 10*.30103

+3.0103= 10*log(2watts/1watt)

so dual the power you get 3db"s

so dual the sound you obtain 30dbs and p2 is 1000 time p1

+db= 10*log(p2/p1)

+db= 10*log(1000watts/1watt)

+db= 10*log(1000)

+30= 10*3
