My ENT made plugs that are so effective I have to remove them or wear electronic amplified muffs over them to here range commands.
If you are plugged, muffed and a 28” .22 lr is damaging your ears, you might need to quit shooting or move to another State and get one of these.

FWIW the one on the left is a PCP pellet gun and can do lots of jobs the .22 can and is legal in your State, so that is also an option.
