Yes hearing aids can easily go through security checks at the airport.
You can wear your hearing aids through security and on the airplane and there's no need to remove your hearing aids when going through airport security.
Airports have no restrictions on hearing aids being worn or carried through security and onto the airplane and if you need your hearing aids you can just leave them in your ears and go right through security with them on.
I've never seen anyone who was wearing hearing aids remove them during the security check at the airports I've been too.
They just go through security like they would without them and never once had they removed their hearing aids.
