Finally done! But still needa fix it!

Finally, Noise Pollution Index was a wrap on 23/4 and presented. But there is still some problems of the use of the amplifing sound circuit because it doesn't work! I need to try again on fixing the complicated circuit or simply just use the external power (i.e. not powered by Arduino) with or without the amplifiing circuit.

Let's see the presentation LIVE!
