Nokia Phones Can result in a Quieter Life

One of the criticisms of cell phones is that they are major noise polluters, and most people discover few things are more irritating than incessant mobile phone users and irritating ring tones. Now, in a complete U-turn, smart phones such as the Nokia N97 are being used to beat noise pollution.The EU now requires every one of its member states to map the volume of noise present in its cities. It is very expensive to deploy and monitor countless noise sensors and the use of computer models to estimate the amount of noise generated from major sourced is not very accurate.In over to overcome this, an application called Noise Tube has been developed. This is an app that you can download on to your Nokia or other Smartphones that will turn the phone into a noise monitor.It uses the phone's microphone to record the noise, and the GPS to record the location of the reading. It is achievable to increase the information manually, for example whatever it is that is making the noise. All this information is then downloaded to the Noise Tube server.All this data is processed together with information on local winds and other meteorological data, and it is provided in a format that can be viewed using Google Earth. Currently this can only be applied to some Nokia Smartphones along with specific Sony Ericsson phones, and each model has to be calibrated before software is released for it, though the developers will work on automatic calibration systems.
