What type of cannon combustion, pnuematic, hybrid?
combustions are normally loud. Pnuematic ball valve canons arent loud. Neither are sprinklers but if you have a piston they can be.

If you have the right chamber to barrel ratio, no. It will be powerful, so i wouldn't recommend shooting it. But no, it you have it right it wont be loud.
If you want it to be 100% totally silent, then don't put any fuel it. The only drawback is that is drastically reduces muzzle velocity.

its a combustion, and what do you mean "no fuel" how will it shoot then?

Ya, don't put any fuel in the chamber and see what happens... You can make a silencer for it, I have never done it, but I know other people have and they say it works.

I have to chime in here "hi", that was a good one! It wen't over perfect.

More dimensions, please:
1) Length of the 3' section (this is your chamber, right)
2) diameter of the barrel
Oh, skip it... I probably won't be responding to this thread again.
Here's some math:
(chamber length)*(chamber inside diameter)*(chamber inside diameter)
------------------------------------------------------------------------------------
(barrel length)*(barrel inside diameter)*(barrel inside diameter)
(the horizontal line indicates devision)
This is your chamber:barrel ratio. (here after: C:B ratio)
If your C:B ratio is below .8:1 (the formula would give you the number ".8"), make your barrel shorter. (you'll increase performance)
If it is exactly .8:1, you shalt note very little noise
If it is 1.5, it's going to be fairly loud
That's as many examples as I'm going to give... just guess at the loudness of other C:B ratios.
Loudness is generally subjective anyways, unless you happen to have a microphone suitable for recording noises this loud, and a standardized tone to calibrate it with.
