 Hearing aids, once again, can only help the health of the ear that you put it on. So it's up to the healthcare professional to decide, is that hearing aid going to help that ear, or do we need to do something similar to what you have, like a bicross, where one is your transmitter, picks up sound, and sends it to the other ear. So there's lots of options, and it's very individualized, and it's really just dependent on what you can recover to.
