WHAT CAN WE LEARN FROM LISTENING TO OUR CITY?
A look to see if we can assess a neighborhood's health by listening to it, by tracking noise levels and overlaying it onto a city map, in heat maps or elevation based on loudness.
CALL FOR PILOTS
This is an Android OS data gathering tool which allows you to contribute, with others, in crowd-sourcing the data collection around Milwaukee.
FUNF - An MIT created data logging app leveraging Android's many sensors.
- Easy Distribution
- Fully transparent
- Simple Opt-In / Opt-Out process
WHAT DOES THIS APP CAPTURE?
What it logs:
- GPS Lat/Long
- Audio MFCCS levels (a range between -1-100)
What it doesn't log:
- Personal data
By using a mobile app we can easily distribute and start capturing information to prove out the concept at zero cost. The more data the better - crowd sourcing can immediately start returning stats on neighborhoods to quickly validate this research.
HOW DOES IT WORK?
This application runs in the background of your Android smartphone and takes data snapshots of your location, time and audio levels roughly every 5 minutes. Indoor noise data is inevitable, so you may have to just get out of the house more and enjoy your community. The application is also set to be mindful of people's data and battery by only uploading its data logs when it is connected to Wi-Fi - NOTE: This app will still effect the battery as it is making often GPS calls. When the device is connected to a Wi-Fi network, that has internet access, the application encrypts the data and then sends it back to a private data server. That data is then decrypted and saved into a SQL database. These data points can then be overlayed onto Google Maps to visually display noise levels throught the city. The uses for this data are yet to be discovered, but one easy potential is when looking to purchase or rent and new home. Once this data is collected and the project is complete, all data will be made available to the public.
HOW CAN I HELP?
Download the app, then go outside and take part in your neighborhood. You can help collect data for this project simply by accessing this site from your android phone and clicking the install button above. Once the application is installed it will immediately start logging and uploading to our server. Take into account that this application can tax a battery and may effect devices differently. If for battery reasons or any other, you can leave the project anytime by going into the app, once it's on your phone, and tapping the 'Uninstall this App' button. Once it's loaded, it's running so go for a walk or just go sit outside.
