We can't hear sound lower than about 20 cycles, but we can definitely feel it through bone conduction. If you want to test this phenomenon, put in some foam earplugs and put on some firing range earmuffs over that, so you can't hear a damn thing, and then see how well your hearing is protected when you stand next to a cannon blast.I'm not sure if bone conduction applies for frequencies over 20K, but that's not to say there aren't other bodily ways for supersonic frequencies to reach our inner ears.
