Calmness Counter

Life in a classroom can sometimes get hectic and noisy!  This free tool might be the answer to try and control some of the chaos.  This is really cool especially if you have a smart board in your class.  You plug in a microphone to your computer, go to this website and it actually measures the amount of noise in your class with an easy to read gauge.  You can set the sensitivity to the level that you want and it will clearly display if the noise-level is getting too high.  Amazing!
