Hi!
Thank you for reading my article–@Deaf_piper, cochlear implants are indeed low resolution hearing. If they were high resolution, you’d be able to hear in music and speech in noise at rates of typical hearing people. There are many factors that play a role in this–the cochlea has 3500 hair cells that detect sound. A cochlear implant at most has 20ish electrodes. Electrical hearing is FAR different than acoustic hearing. The key concept is thinking of information transfer with electrical hearing as water flow in a pipe. There is much more information that can be transferred with acoustic hearing–a large pipe, so to speak. Electrical hearing is useful, but carries nowhere near the amount of information. It’s just the way the nerve works. You hear two ways–with place, where the cochlear implant electrode is located and timing. In typical hearing, the auditory nerve fires at the rate of the frequency of sound. This provides the timing cue. With electrical hearing, the place is “smudged” because electrical current spreads. But few patients realize that the timing is waaaaay off. Electrically stimulated auditory nerves don’t fire to the frequency of the incoming sound. So you lose this HUGE cue for deriving the frequency of incoming sound.
That’s the short version. People dedicate their lives to these issues! Hope this is helpful!
