NoiseManager

Do you want to know how much noise around you? Are you willing to share the measurement with others as well as view the data collected by others?

This free and brilliant app not only achieves the above goals but also allows you to see complete data on the map. Whenever you want to measure the noise level, just run this app to start probing. It uses four different colors to represent the noise levels from low to high. At the same time, the location data will be gotten in order to show on the corresponding position. To protect users’ privacy, the app processes both sound pieces and location data before sharing with other users. In a word, the app enables Android users to detect noise levels in a simple way without leaking any private information.
