Last night in our league ball game while my DD was pitching to our catcher, the batter fouls off the pitch and it hit the catcher in the front side of her face mask. She (the catcher) immediately puts her hand to the ear hole and comes toward me crying. The "pop" off the helmet was so loud that it caused her to temporarily lose hearing in that ear for a while and had a ringing sensation. She finished out the inning /game but was still visibly shaken even after the game was over. Her mom sent us word that her hearing came back and the ringing stopped later that night but she did have a little head ache. She did not have any signs of a concussion at the time of the hit or after the game. I looked at it like someone shooting a gun next to a person without hearing protection. Has anyone ever witnessed this before with their catcher?
