Pretty sure this is also why, when you stand at the right spot in a techno concert, the music starts to sound like a jet engine.

We also have this in game development, where if two sound effect emitters play the same effect at the same time with just a bit of offset, phase, whatever, they sound like that.

If the offset is fixed, the effect is called a comb filter. If the offset is changing, the effect is called flanging. The name stems from recording engineers rubbing their fingers against the flange of a reel-to-reel recorder's tape reel, to brake it slightly, which adds increasing delay to the sound.

Huh so a flange is just a combing effect that shifts around? I'd never considered this. Also neat fact about flanges, didn't know that either. Thanks!
