Well, no one with a CI disagrees with that.
I'm a CI wearer and I can assure you that you can take it off just like you can with a hearing aid
I love the silence at nights and am not anxious to listen to my husband snoring
I also have a friend who never heard sounds before and then got a CI several years ago as an adult. The CI didn't work for him because his brain didn't know what to do with the sound, as he had never heard it before. So after a year, he stopped wearing the external processor. He doesn't have any regrets for having tried it and he doesn't need to have surgery to remove the internal implant.
Yes, I agree that every individual is different. Me, it was too painful to wear hearing aids due to the damage inside my ear and they gave me terrible tinnitus and dizziness. Getting a CI overcame that problem. Please do not assume that just because we have a CI, we don't accept ourselves as deaf people. There are many reasons why someone might go for a CI - a hearing aid may not even be a choice for us. They work differently.
