Cochlear implants are a form of this, and are already commercial. I remember having a conversation with a guy at a doof about 10 years ago, standing right near a loud sound system, and it took me 20 minutes to realise he had one. He was completely deaf without it on.. I can only assume the tech is much better these days.

Similar things exist for vision (though maybe not yet commercial?).
