Turn your mobile phone into an environmental sensor and participate in the monitoring of noise pollutionNoise pollution is a serious problem in many cities. NoiseTube is a research project started in 2008 at the Sony Computer Science Lab in Paris and currently maintained by the Software Languages Lab at the Vrije Universiteit Brussel. The NoiseTube project proposes a participative approach for monitoring noise pollution by involving the general public. The NoiseTube mobile app extends the current usage of mobile phones by turning them into noise sensors enabling citizens to measure the sound exposure in their everyday environment. Furthermore each user can participate in creating a collective map of noise pollution by sharing geolocalized measurement data with the NoiseTube community.By installing the free app on your smartphone, you will be able to measure the level of noise in dB(A), and tag the measurements obtained (e.g. subjective level of annoyance, source of sound,…). When uploaded to the website (3G, wifi or manually) you can check the sound trajectory of your recorded measurements on Google Maps.

Many recreational activities are accompanied by loud concurrent sounds and decisions regarding the hearing hazards associated with these activities depend on accurate sound measurements. Sound level meters (SLMs) are designed for this purpose, but these are technical instruments that are not typically available in recreational settings and require training to use properly. Mobile technology has made such sound level measurements more feasible for even inexperienced users. Here, we assessed the accuracy of sound level measurements made using five mobile phone applications or “apps” on an Apple iPhone 4S, one of the most widely used mobile phones. Accuracy was assessed by comparing application-based measurements to measurements made using a calibrated SLM. Whereas most apps erred by reporting higher sound levels, one application measured levels within 5 dB of a calibrated SLM across all frequencies tested.
