I used to play the trombone, so I’m tickled by this report: an acoustic shock wave has, for the first time, been filmed emanating from a trombone. It’s not super-visible; you might need to watch fullscreen to see it.
Also, a warning: this will only be interesting to vibration nerds (and, possibly, trombonists). The rest of you will be underwhelmed.
It’s the long tubes in the slide of the trombone that allow this sort of shock wave to form. Other wind instruments, like tubas, have longer wind pathways, but they curl around more.
