Environmental noise is one of the most present pollutants in the world today, with potential negative impacts on your health. The NoiseWatch app uses the built in microphone on your hand held device to determine the level of sounds it detects, and displays this in decibels (dB). Share you readings in the NoiseWatch web app http://discomap.eea.europa.eu/map/NoiseWatch/ and learn more about noise at European Environment Agency http://www.eea.europa.eu/themes/noiseIf you share your measured noise level on the NoiseWatch web app we also encourage you to indicate the source of the noise and if the measurement was taken indoors or outdoors. Based on this additional information we can build interesting maps based on the data we get from our users.Key feature:Calibrated noise meter
