Sounds added to Google Street View

Google Street View lets people explore the world from the comfort of their living room, but it can’t replicate the experience of actually being there.
In a bid to make this the mapping service more immersive, designers have created the Sounds of Street View project, which adds audio markers to locations.
As people move around the map, the sounds change depending on what they are looking at and this includes church bells, waves hitting the beach, a fairground, and more.
