Site-hearing
Site-hearing is a website that logs places that have interesting acoustics all over the world. All these sites are plotted on a Google map, and can be sorted by type.
The maps includes ancient sites, acoustic accidents, research facilities, filming locations, whispering galleries, and installations, among other things, and it's always growing. As I find out about more and more fascinating places through my research, I need a place to keep track of them all, so they all might inform each other and my own work.
