Sound Pollution on Google Maps

AirCasting is a platform for recording, mapping, and sharing environmental data using your smartphone. Currently, AirCasters can upload sound level data recorded by an Android app.

AirCasting currently maps noise levels but there are plans to expand the range of devices that plug into the AirCasting platform to include pollution sensors. Currently the AirCasting smartphone app lets you capture real-world sound measurements, annotate the data and share it on a Google Map.

You can view an example of AirCasting in action on this Times Square to Central Park map. The map shows the noise levels recorded on a walk up 7th Ave from Times Sqaure. Using the map you can see how noise levels are very high in Times Square and again at 57th Street before dropping almost immediately upon entering Central Park.
