Perfect for my purposes...almost – NoiseLevel Review

Like most my kids love to play video games. The games are always loud, so my wife any I thought we'd be smart and get them some headphones to use playing games. So now with the headphones, we don't have to listen to the loud games. But the problem with the headphones is that they can't hear themselves talk, so they talk WAY TOO LOUD. NoiseLevel gives me a perfect visual indicator to place in front of them while they are playing so they know just how loud they are really talking, and they manage to keep their voices at a reasonable level. Now my only problem is that after 30 seconds or so, the iPhone goes to sleep. So please provide an option to keep it from doing so.
