Perception and Watts: Doubling of power
There's a curious rule of thumb, which to my ears seems mostly true:
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?? 😁
Hey @fuzztone , based on you asking questions like "Why do I care" on another thread, it may be helpful to remind you that this is a community driven site and not one you pay for. If you find threads you are not interested in feel free to ignore them. You might also want to take a look at the number of others who have participated in these threads and think "well, others are having fun so I should let them." Just a thought. |
