I just went to get my hearing checked for the first time, and it's <i>fine</i>, the doctor said my responses are great for someone my age.<p>But in a noisy environment - not even <i>that</i> noisy, just kind of any noise at all - I'm functionally deaf. My child was telling me something while rubbing two balloons together and I had to get her to put them down before I could parse what she was saying.<p>I know there's obvious privacy issues with this thing, but man, it would be great to be able to pop in a pair of earbuds and be able to <i>hold a conversation with someone while cars are driving nearby.</i>
