The French did the research ~ '60s. Ethics quiz in box.
iirc. I saw pix, read articles.
~54 IS the res. freq. for (most) anal sphincters YMMV. And a hi-enough level WILL do exactly what you imagine.
Now for pretty-Quick death - prolly sweep from 50ish on down. Find res-freq. of adrenals, liver, heart etc. along the way. Shake loose and more. Just a matter of time/intensity chosen. There is NO credible data on the Gaussian spread, MLDs (min. lethal dose): for fucking Obvious reasons, I'd opine.
French built a battlefield weapon, a Medusa-headed monster capable of creating such levels. Probably killed a few cows, pigs, Murican tourists tryin ta touch the Mona Lisa's frame -- and other undesirables.
Prolly best forget conventional Helmholz resonators and variant 'speaker' transducer techno. Compressed air is the coupling, when at such humongous amplitudes. A size consideration, among others..
No, I haven't followed-up on 'progress' since. But simple physics shows it obviously possible, and how to do it. Where there's a will... (And we all know where the $ \ufffd are always spent FIRST: more effective killing.) It's virtually the Hallmark of our er civilizations. Resonance! - now we can kill with 'music' too. After all,
God is Love. And we surely are a God-ly People, to hear us tell about it..

Ethics quiz: is it more merciful to kill millions slowly via Big-Mac ads with toys to lure kiddies and form their eating habits? or - to make Medusa-headed music-killers - which operate more er locally, but quicker?
Extra points for brevity & clarity, you lawstudents.
