What's That Sound? Two Tools Track Noise Pollution.

From traffic to construction to everyday chatter, noise pollution is a part of city life. But with the ubiquity of mobiles, documenting noise pollution is getting a little bit easier. NoiseTube and LHR NoiseMap are two projects that use mobile phones to record and map instances of noise pollution.

NoiseTube uses crowd-sourcing to monitor noise pollution. Users with GPS-enabled phones can install a free application that measures the noise level wherever they are. Users tag the recordings with a description of the noise, its source, the time of day, and other criteria, and the data is then mapped onto GoogleEarth; in this way participants can use their phones as noise sensors to automatically share information about their city with other members of the community.
