Needs more features

I like this app but feel that theres room for improvement. With the simple addition of "About Noise" and "Tips", the app would be way more useful. For instance, is 85 decibels a noisy environment? How loud is too loud? And is there an optimal way to position the iPhone to get the most accurate readings (where is the mic anyway)?

That said, its an elegant, simple app that Im keeping. Just that it could be even better with more info.
