I vaguely remember something from about 30 years ago, where they were
using focused ultrasound to break up kidney stones. It looks like the
technical term is focused ultrasound lithotripsy. My recollection is
they used a high voltage spark for the sound source.
High voltage spark sounds like it would be in your wheelhouse. Might
not work, but still sounds like fun.

What's this for anyway?
Big sharp noise through a pipe is what I believe you said you
wanted.....but what is the purpose?
I suppose a gunshot sounds sharp in human terms, but it's really
rapidly expanding gasses being released. In hindsight it makes sense
that there would be an initial burst followed by diminishing secondary
noises. If that's an issue, then aren't echoes in the pipe an issue
too? I don't see how you would avoid the echoes.

Walther handgun will not fire power hammer loads. Does not seem

But a 1908 Savage rifle will.
Seems gunshots are not a sharp impulse. Just a burst of noise I
have discovered. No where near a perfect impulse.
So having fun and probably scaring people driving up the highway
but on a quest for a high quality shock wave/sound impulse.
Recording engineers use balloons and clappers.
I have a high power speaker driver coming. Going to see what
happens when I get close to blowing it out with a capacitor
discharge.
