I just saw this amazing video courtesy of NPR about Schlieren Flow Visualization. In it you can actually see a sound wave form and spread as it propagates through the air.

 

What an amazing technique!

If you don't have the set up to produce those wonderful images of sound traveling through the air, you might want to check out some jewelry from our Sound Wave Collection. We have the words "I Love You" in ten (and counting) different languages frozen in silver so you can wear them around your neck or whispering in your ears.

We can also do custom commissions using your voice so you can give an extra special gift to someone you love!

Isn't sound fascinating and beautiful?
