  I can see only in a limited area at any given time, but I can hear in a full sphere around me simultaneously. I don’t think it’s accurate to characterize such a large area as “the periphery”. One sense is imprecise and covers pretty much everywhere while the other is detailed, but very limited. Both senses work in concert to build a full map of the world, and the loss of either is concerning. I’m more comfortable in a blindfold than isolating headphones though, because I can still echolocate while my vision is impaired, but my vision has no way of emulating hearing’s function. I’d have to be constantly looking around all over the place.

  While sound is not nearly as dominant, it’s absolutely not just a backup sense. It’s the fastest perception we have (the best rhythm game players can play blind but not deaf), it covers all directions, and even in our sleep we still respond to loud sounds.

  Sound perception is so fast that it’s often what directs you to look in the right direction, even if what you’re reacting to happened in your field of vision.

  Funny enough, even our peripheral vision is faster than our central field of vision, to help us avoid predators coming from behind! Our forward directed vision is for tracking and understanding what’s in front of us, sound and peripheral vision is in large part for environmental awareness. They’re co-dependent!

  Humans can even learn echolocation!

  Hearing is a backup sense.

  That might vary by person, but for me it’s not. If I had to pick between being able to see and being able to hear, it’d be hearing, hands down. Being able to see is amazing and I’d miss it, but hearing is just a whole other dimension.

  Being able to know how someone is feeling, just by hearing their voice. Listening to music and hearing all the shapes, colors, and feelings that come with it. The colors aren’t always ones you can see, like blue or yellow. It’s hard to describe. I’ll close my eyes and just listen at a concert (not the whole time) and same with TV, a lot of times. I usually remember it better that way.

  If I have to find something in a backpack, I’ll often do it by feel. I probably look like a raccoon washing its food, but it just works for me. You can tell things apart by feel and sound.

    That’s neat.

    It makes me wonder if your hearing is better than average or if your eyes are worse, making it not so clear-cut.

    Do you need glasses, or have you ever had your hearing tested for whatever reason?

  I have heard that the incidence of suicide is higher in deaf people then in blind people, which would suggest that, while our senses are sight dominated, losing our hearing has a bigger impact in some way. That said I can’t find a citation for that, so make of it what you will.

    This is the best I could find on the specific topic: pmc.ncbi.nlm.nih.gov/articles/PMC7888369/

    People with visual or hearing sensory impairments had twice the odds of past-year suicidal ideation (OR 2.06; 95% CI 1.17 to 2.73; p<0.001), and over three times the odds of reporting past-year suicide attempt (OR 3.12; 95% CI 1.57 to 6.20; p=0.001) compared with people without these impairments. Similar results were found for hearing and visual impairments separately and co-occurring.

    Or maybe the blind people just miss more.
