Perhaps you can't get out and see the world right now, but here's a way to hear it! Prof. Trevor Cox of the University of Salford in the UK has created a website of remarkable sounds from taround the world. Explore the Sonic Wonders map at http://www.sonicwonders.org/ .
In addition to being a lot of fun, there are some exciting bits of acoustical physics to explore here! Check out whispering galleries in Massachusetts and New York; resonant sound sculpture in Iceland, booming and whistling sands around the world. The site is well worth checking out if you're curious about sound - or teaching about it!
