[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?

Everytime that main gun fires, the crew get their bells rung. 2x for the driver if the hatches are open. Being near cannon that size cause little TBIs everytime its fired
