Noise for airports is a blog about culture, sound, music, and technology.
You can filter the posts to see just things I wrote or made.

From Boing Boing, ACOUSTIC LEVITATION. Sounds that are so loud that when adjusted to form standing waves, their nodes can support light objects in the air.
This is a great example of how sound is actually a physical, material phenomenon. People so often think of sounds as immaterial or transcendent or intellectual objects, but here they are, just picking stuff up. An interesting corollary to the use of sound as weapon.
