Perception and Watts: Doubling of power


There's a curious rule of thumb, which to my ears seems mostly true:

  • To double the perceived volume, you must output 10x more power.

10x power = 10 dB by the way.  We've read this as we were buying amps and trying to decide between 100w/channel and 150w/channel.  We are told, repeatedly that 50 W difference isn't really that much.

On more than one occasion I've tested this and found it's pretty much spot on.  Here's my question:

How can any of us really tell what half as loud, or twice as loud is?

I mean, think about this for a bit.  I cannot tell half as bright, or twice as bright, but it seems I actually CAN tell what half as loud is.  How does this even begin to work in the ear/brain mechanism?? 😁

small speakers. use 650W monos.

amazing presence, air, and overall sound.

i can't get any louder, as speakers would explode.

motorhead, tank, anti nowhere league, detente, dark angel, GBH, exploited, pestilence, Y&T, Venom, sound SOOOOOOOOOO much better at max volume!

 

power is your friend, never have i clipped the amps, never have i ever heard any slight dip in sound, nothing but constant bombardment of russ andersons vocals as clear as if he was in my room.

this is what power gives you, no slowing down, no muddy anything, just pure bliss never any restraint, or sound of of straining, what so ever. sure bigger speakers would benefit (as would I) from power, but the ones I want are much to much for me, hell, the speakers i would love, are 2-3 Xmore than my truck and suv combined. 

we must make do with what we have.

enjoy the tunes!
