NoiseCapture is Android App dedicated to the measurement of environmental noise using a smartphone. The goal is to produce relevant noise indicators from audio measurements, including a geospatial representation. Measurements can be shared with the community in order to produce participatory noise maps. NoiseCapture App is a component of a global infrastructure, i.e. a Spatial Data Infrastructure (SDI), called the OnoMap SDI, that allows to process and represent the geospatial information, like noise maps.
