<SMALL>uuuhmm, where can I get some of that "decibel"-stuff?</SMALL>
Martin, just got back to the computer and wasn't expecting a reply:
Three mikes, one at the bass drum, one at the snare, and one at the tom-tom should give you all the "decibel-stuff" you want.

I've seen (heard) it; no kidding.
I used to be a nitwit myself. I used to drive my parents insane practicing at home with my loud volume on my steel guitar, in my early teens. Most of the communication with my parents from about 13 years old to 19 was,
"Ricky, turn that thing down".

I just about drove them out of their home.
But, playing out with a group, I've always had consideration for the singer and the other band members.
Change of mood, in the same tune, adds a lot to the presentation of any song or tune. I've heard drummers who hit cymbal, bass drum, and sticks on the snare, on every beat of the tune, while backing the singer. To me, this is like a steeler playing the melody without cease, while the singer is singing, instead of fills and runs.
When the drummer does a solo, be as loud as you want. At certain emphasis points in a song more intensity may be in good taste. But, this __ electric bass and drummer competing with the singer and lead instruments for the lead is in bad taste. It's as if they aren't even listening to themselves play, or thinking about what they are doing, and are not thinking about the presentation as a "whole". And, I hear a lot of it.
