Currently when my tank is hit but not penetrated I hear a sound and that’s it.
Imo it would be nice to add a minor concusion effect and a better, more powerfull sound. Their power would depend on the shell that hit you and your armour.
So heavy tank hit by small shell would have very small or even no concusion.
Light tank that blocked big shell would get big concusion (but still smaller than after penetration).
The goal I have in mind is to create a feeling of “you just got a second chance to live”.
