Listen up. Environmental noise is one of the most present pollutants in the world today, with potential negative impacts on your health. The Noise Meter uses a built in microphone on your hand held device to determine the level of sounds it detects, and displays this in decibels (dB). It has been designed solely to measure noise levels wherever you are.
Send your readings to be displayed on the NoiseWatch web app at the Eye on Earth global public information service for creating and sharing environmental information.
