Just curious, can you explain what you mean by CIs being crappy, or point to an existing explanation?
- hprotagonist 9y agoBriefly, you get 16 frequency bands if you’re lucky. A healthy ear has about 3,000. It’s more complicated than that, but in a nutshell, the fidelity with which CIs can represent the world is very limited. They work for speech, mostly, in quiet. There are simulations of what they sound like on YouTube, somewhat.
- Kluny 9y ago"Crappy" is one way of putting it. Those 16 frequencies, for me, are the difference between a life worth living, and a life in crippling, hopeless isolation, ended by suicide at an early age.
- akvadrako 9y agoHum... I'm pretty sure my life wouldn't be much different if I could only communicate non-verbally.
- hprotagonist 9y agojust to be clear: i’m not knocking their utility! many normal-hearing people just seem to believe that CIs are bionic ears with perfect performance, though, and that’s manifestly false. the CI users know are glad to have them, and they are, as you say, a lifeline for many. i’m glad my research ultimately contributes to better ones. we just have a long way to go.
- LX8DvZFL 9y agoThis needs to be more widely known. You'd think from reading marketing material that you would be listening to Mozart and jazz the week after implantation. The reality is that you have basically no pitch perception. 16 frequency bands across, say, the four octaves that music is interesting? You're lucky to discriminate half-octaves let alone semitones. Temporal aspects of music come through alright. I suppose you could be a drummer.
- AstralStorm 9y agoYou would be surprised. Closer to 100 or 200 bands actually, overlapping. There is a plenty of redundancy. The number cited is about the number of neurons.
- hprotagonist 9y agoI am not sure I agree with you. Given that you get ~16 electrodes, and some greenwood-like frequency-place map along the basilar membrane, and given that the place specificity of stimulation from those electrodes is significantly larger than the width of an inner hair cell, I'm not really seeing "200 bands".
