Same speed (below sound barrier), same barrel length. If you could have same ratio of supressor volume compared to bore...

I have no idea, but it would make for an interesting research project...

I suspect if you were to scale everything up properly to drop the muzzle pressure to the same level, the big bore would still be louder. The exit is still like 0.2 square inches on a 50cal hole vs 0.075 on an 8mm, so would that mean a 2.67x more powerful sound wave?
