I recently found myself between two of those giant vacuum trucks, both sucking material out of underground electrical vaults, about 100 meters from each other. The sound waves at my location were making a really cool interference pattern, as the frequencies from the vacuums were very close, but not quite the same. Thus the waves were at times canceling each other, and at times adding to each other. A pretty cool effect. This clip is about 1:36, and is my favorite of the three recordings. At 1:32, one of the trucks shuts off its vacuum. I just recorded this on my phone, and did not do any editing.
