The Vuvuzela and Complexity

As almost everyone now knows, the vuuzela is a noise maker used at sporting events, especially the World Cup matches. Its use at events is controversial. The sound pressure one meter from the horn is at the pain threshold, and when played in unison, in a stadium of 100,000 drowns out everything.

When played it produces notes around 235 and 465 Hz. In aggregate, the sound is like a very large angry bee hive.

I wonder if the aggregate sound is random or complex? Does it have structure like a fractal?

And, I wonder when things like the equivalent of the wave will start. I'll be really impressed when something like a beat or rhythm emerges.
