A new app called by the name of NoiseTube has been launched for iOS and Android devices. Apparently the app is capable of sensing the strength of the noise around the user. Basically, what it does is measures the noise in dB. It's quite not sure how is the app going to be of any help to a normal person.
However, users will need GPS as well as a properly functioning microphone on your handset in order to get going. The NoiseTube app shows decibel levels in green or red colors depending on the severity of the surrounding disturbances. It is available on Google Play Store as well as iTunes. It works with the iPhone 3GS/4/4S/5, Samsung Galaxy S2, Dell Streak 5 Mini and HTC Hero/Desire HD/Desire S/One X.
Once you're done recording an audio clip, it can be uploaded to the server over the web and then a detailed noise map of sorts is provided for you to examine. Created by the Free University of Brussels in Belgium, the tool is simple to use since it is meant to help the general public and not just tech-savvy folks.
According to the developers, NoiseTube helps by assisting communities monitor the noise level in their respective localities and do something about it, because everyone knows how stressful loud sounds can be to the mind and body. The app is supposed to enable a participative approach towards checking noise pollution.
