I had my surgery done at Mayo in Rochester Mn last July. My audiologist there said I could do the exercises provided by Coclear but that he felt they were not important. His comment was that the way to rehab to gain hearing clarity was simply to use it! The more you got out, listened to people or speakers, took walks to listen to sounds in nature - simply keep your processor on always unless sleeping and showering. That’s worked super well for me. The first week was sometimes a bit overwhelming with all the strange robotic sounds but within 2 weeks, things were sounding much more normal. So glad I got the surgery!
