A mobile app allows citizens to map the noise pollution in their cities. Developed by researchers in Belgium and France, Noisetube lets urban inhabitants to document noisy areas with their smartphone.

Compared to street noise, other kinds of pollution typically get more attention. Luckily this is an issue ordinary people can take into their own hands, as this app lets them record and map sound levels in their area. A citizen-run network could complement existing government noise-measuring methods, or replace them all together.

By using smartphones as environmental sensors, the need for expensive measuring gear is eliminated, as is the challenge of sensor distribution. The noise pollution app not only allows you to upload sound level data, it also lets you annotate as you go.
