We've just caught wind of a new app for the iPhone / iPod touch should you be either a little hard of hearing or a little nosy. SoundAMP works a lot like those Sonic Earz you see on the infomercials -- you run the app with your earbuds plugged in, and then sit back and enjoy listening to the sweet sounds of whatever's going on around you -- only louder. The app allows you to control volume and tone, and you can also replay the last 30 seconds of what you've been hearing -- in case you missed something particularly juicy. Now, personally, we put in the earbuds and crank up the tunes to shut out the outside world, but if this is your kind of thing -- it's available in the iTunes store right now for $9.99.
