I heard 150db at the bell not 200db. What was your source for that number?
I don't recall the figure but it is quite high.
This high speed video captures what they called a shock wave produced by a trumpet however a traditional shock wave is visible on the rarefied side.
The second video is a system i developed the transducers and control electronics for which here is operating in the mid 160dB's at about 21Khz and at least up to 175dB, i never saw any kind of shock wave even at those pressures (although at 175dB one could light a cigarette with acoustic friction).
I don't remember, it was a long time ago. Anyway, I play the trumpet, and it can be VERY loud at the bell. Heck, it can be very loud 15 feet away. I went to a clinic/master class given by Doc Severinsen about 3-4 years ago. He picked up a student's horn, pointed it right at me, and darn near parted my hair with a scale going up to high C.
