I’ve struggled for years to articulate what being hearing impaired and deaf was and is like.
The first video1 demonstrates what I heard with hearing aids. When I was 13, I got a cochlear implant. At that time my hearing with a hearing aid was somewhere around severe on the video’s scale.
The second video2 is what I heard with a cochlear implant when it was first turned on and for the first few months. Somewhere along the way the mental switch flipped and I just hear it as sound instead of a set of beeps and tones.
I now hear between most of the frequencies I should be expected to hear if I were a person with normal hearing. Because I never had the full range of frequencies as a kid, I never quite got and still don’t really have the mental map of what sounds are a given thing so I still rely on lip reading quite a bit and avoid using the phone and require captions or subtitles for movies or videos. If you ask the people who know me, I speak intelligibly and can usually make myself understood, and can understand what they say pretty well.
