Ah, no. It's double the intensity. You need 6dB to double the SPL.

All academic anyway. If the -peak- SPL exceeds 140, you going to suffer damage with impulse noise. 16" v 22"- both are going to do your hearing in eventually if there is no can or ear protection.

Trust me, as a retired audiologist, I've fitted HEAPS of hearing aids to old shooters. It's no fun having that sort of loss.
