Can someone tell me what gives a cannon that low pitch, hit you in your chest, thunderous boon? I have seen small bore cannons that sound more like a musket then a cannon. On the other end, I’ve seen full size mortars that are loud but don’t sound like cannons.
I suspect the answer will come down creating a balance between bore diameter and bore length. For a specific bore diameter, you will need a minimum bore length to produce enough compression to give a good boom? Following this thought, the bigger the bore diameter, the longer the bore has to be to create enough compression. If I’m on the right track, their has to be some hard and fast rules governing bore diameter to bore length to create a good boom. Of course the bigger the bore diameter (as long as the bore length is proportional) the lower the pitch of the report.
So tell me, when looking for a cannon barrel, are their any hard and fast rules I should know. I’m looking for a cannon that sounds like a cannon, not a musket or a mortar. As a frame of reference, I don’t need anything as thunderous as a full size cannon but more like an outdoor sporting event cannon.
I’ve got my eye on a 2,25" Mountain Howitzer LOA 16.437” Barrel 2.275” x 12” Powder chamber 1” x 3” mostly because of the inside bore diameter. If I’m reading it correctly, this cannon has a 12” inside bore that is 2.25” wide. Will 12” be enough bore length for a 2.25” bore diameter to create enough compression for a low pitched, sounding like a cannon, thunderous, BOOOOOOOOOOOM?
Thanks,
