Audio-related questions
On top of what Andrew has mentioned, if you ever take your gear outside and listen from distances of 10m or more, and you calculate a 6dB drop every time you double the distance then...

110 dB at 1m
104 dB @ 2m
98 dB @ 4m
92 dB @ 8m
86 dB @ 16m
80 dB @ 32m

So it isn't hard to see why you need thousands of watts at concerts or hundreds of watts in a large room or night club.
