I wonder how long it will take her to get used to it (being able to hear) and how much it will drive her crazy, at first.
I remember when my grandfather got his hearing aid. He heard sounds that he had not heard for 30+ years (clock ticking, kids laughing, dogs barking in the neighborhood)
He said that it sounded like noise and distortion, at first, and was a whole lot of input to process.
I guess it is only a matter of time until they put these in the ears of special forces types so inbound comms are silent...
