where you get that math?
the Classic Myth busted.
here goes
Question ---I bought a 100-watt amp because my 50-watt wasn't loud enough.The 100 is louder but not by much. shouldn't it sound twice as loud?
Answer---No,When it come to sound the logic of 1+1=2 won't work.
A human preception of sound is a "logarithmic scale". People do not hear sound linearly. so doubling the wattage only increases by 3db.,what you might call a noticable difference. every ten db in gain is percieved as a doubling of loudness to the human ear. So a 100 watt amp is only 3db louder than a 50,a 200 watt amp 6db and a 400 watt amp would be close at 9db.
So the opening band playing at 95db is considered quiet compared to the headliner ripping your ears off at 105db..a percieved doubling of loudness.
