You need to get high tech
When I lived in an appartment, the teenager upstairs from me had an electric guitar which he played a top volume... only problem is that he did not know how to play it nor could he be bothered to learn... I asked politely a few times to keep the volume down but well...
Electromagnetic interference (EMI) to the rescue...
I break out the old HAM radio gear, UHF transmitter, 250w linear amplifier, 14dB directional antenna... stand under his amp, point the antenna and key the mic for a few seconds, get this horrible noise from his amp... he stops playing and restarts, so I key the mic again and hear this awefull buzzing sound from his amp... so I keep it there a good minute... funny thing is that when I unkeyed the mic, the buzzing sound continued

blew his amp. Problem solved...
Did the same thing to a neigbours home theatre in our condo... a$swipe had no consideration for the other owners...
EMI is your friend folks

military has been using it a while, playing with EMI I've even stalled a few cars (seems Saturns and Explorers onboard computers are VERY sensitive to EMI, barely a few hundred watts will shut down the computer, and the car).
