If your neighbor is a music lover and lover listen
loud music, it can punish))
For a start, I bought FM Transmitters,
which can be found in most stores control connection.
There you can immediately buy and the usual power adapter.
Well, then, she was already a vengeance, and quite brutal;)
On the USB-stick it was recorded very loud siren sound as in the bombardment.
When between songs sounded on the radio station's name or frequency of the station,
hammered in the transmitter, the same wave, and a music lover alcoholic gloh of sirens.
Fortunately, the neighbor heard only the radio, so that after a couple of times
siren was enough for him, and after numerous expletives
with his hand behind the wall, he stopped cut in loud music;)
