[ELI5] What prevents tank crews from getting injured from the Shockwave of the gun they are firing?

Question

I have been watching a few videos and I can see that some of the tanks nowadays have such huge main guns that obviously have a lot of power, but what stops the Shockwave from travelling inside and around the interior of the tank where the crew are?

To me that sounds like it would cause a lot of damage with all the vibrations going on. Do the tank crew even feel the brunt of the shockwave?

Answer 1

The shockwave mostly leaves the gun thru the muzzle. The rest will be absorved by the enormous mass of the rest of the tank; only a small portion of the energy will damage the crew’s ears.
