$1 hearing aid could treat millions with hearing loss
I've been using over-the-ear hearing aids for about 8 years and they have become a part of my life, like contact lenses. The technology has improved dramatically but it's simply not fun having something riding on your ear. They need adjustment throughout the day, and now that facemasks are a thing they're always getting snagged. And there are just some situations where they aren't ideal: many people talking at once in different parts of a room, or when there is any kind of heavy background noise (fire alarms, sirens, etc.).<p>That's why the neural implant that Musk recently demonstrated excites me to no end. Everything is inside the body, no need to amplify or filter anything, just interface directly with the nerves and compensate for the damage. I hope I don't have to wait more than ten years to get one.
