The details of the weapon still doesn't seem to be known, but probably just a matter of "when" those leak, seems to be the same as what was used in Venezuela (which Trump might confuse when he talks about it).
I lived in an apartment with extremely thin floors. One night I needed to move the bed 5 inches away from the wall at 3am. In my room it made almost no noise and took 1 second. But, the next morning the woman below came up and complained.
I told her I heard her masturbating often and would just put my headphones on and check in 20 minutes. She said she didn't do that. I said "well, maybe you're listening to porn. All I know is I hear something".
