303 sound

As the guns don't fire synchronized there will be of course parts of the sound cancelled out, parts added up and parts filling the "free"spaces.
That is what i meant, the sound doesn't increase 8-fold, it increases, but without actual measurement one can't say how much.

you simply can't algebraically sum two sound pressure levels. a sound pressure level L1=50db + another sound pressure level L2=50db isn't equal to a sound pressure level of 100db.
The mathematics law governing this phenomenon is on logarithmic base.
The increment should be minor of 0,5db
