Sounds of Street View currently features three Street View locations with sounds matched to them. Hopefully, the gallery of sounds expands soon. If you cannot wait for the gallery to expand, you can attempt to create your own Sounds of Street View.

Applications for Education
Sounds of Street View has the potential to be a good source of virtual tours to use with students. A similar resource that you may want to consider is the Nature Sound Map. In some cases the sound recordings combined with Street View imagery could give students a more complete picture of what it is like to be at ground level in a place.
