Get Rid of Noisy Neighbors: Play Your Music Through Their Speakers

I live in an apartment building, as is typical with most people living in Europe, and neighbors sometimes don’t cooperate, especially when you live in a place like Romania, where most of your neighbors will get drunk around 3 AM and start blasting their music like it’s something everyone wants to hear when they have to get up and go to work a few hours later. Yeah, that’s life, but you don’t have to let them play their music. Right now, I’m going to teach you something simple I learned that lets you blast your music through their speakers, even when they don’t currently play music.

In fact, you could even get creative and let your voice come through and say something like “SHUT THE HELL UP! NO ONE WANTS TO HEAR YOUR NICKELBACK ALBUMS!”

The Process

Here’s what you’ll need to do this vicious act: A CB radio, a bottom-loaded CB antenna, and a linear amp.

Here’s the method: Through amplitude modulation (AM), you could interfere with the frequency your neighbor’s speakers normally pick up sound with, and then you’ll make them vibrate at whatever frequency you want, producing the sounds you desire. It’s kind of like how cell phones make speakers go nuts when someone’s calling you.

And here’s what you do: Hook up the amp to the CB radio, and connect the CB radio to the antenna. Get your antenna as close as possible to the neighbor’s sound source. Turn on all the devices and try playing around with the frequencies a bit. You’ll eventually reach a frequency that you will hear your own voice through as you talk through the radio’s mic. Once you think you got it, find a way to get the most annoying song you can possibly think of blasting through there.

This article is only for educational purposes and some of the things here could be illegal where you live. If you do not know of the legality of interfering with speakers, please do not try this. Keep in mind that, by interfering with someone else’s speakers while they’re not playing any music, you are breaking the law, and I did not write this so you can go around and play your music through everyone’s speakers when they’re sleeping. Also note that certain frequencies can damage speakers permanently. You don’t want to do that, do you? Sure you don’t…

The Tech Guy’s official disclaimer also applies to this piece of work.

Have a nice day!

    When your RF bleeds over to their stereo, does it silence their incoming frequency or does it just play in addition to their music. I have been researching doing this exact same thing for one month now and am ready to buy all the parts but have been looking for some reassurance from some other individuals that have done this. If I were to bleed over to my neighbors stereo, could I theoretically just keep the CB mic activated and just play pure beautiful silence? I want to stop her music not play my own. Could I PM you somehow to talk about this. I am desperate but willing to spend the money to mitigate this issue that is torturing my wife and two babies.

      You can’t play “silence” into another speaker through RF. At best, you can make some weird noises that will make the person on the other end believe that his speakers broke for some reason. This might just discourage him to continue using them. Just play some static on a loop and keep it running 24/7. The only way your neighbor can stop the static is by turning off the speakers, or RF shielding the house.

        Thanks Miguel! I was going to get a cheap Cobra radio and a directional antenna (MaCo VQuad Base Station). I want a directional antenna since I don’t want to piss off any other neighbors. The linear amps a little harder to find. How much modifications does it take to convert a 10m amp to work on a 11m radio? Hypothetically, what if I were to power up a 250 watt amp with the previously mentioned antenna at full gain from 20 ft away and play a continuous 6kHz tone through her speakers? Not that I ever would…

          The entire concept I described in the article is a wildcard, really. You’d have to take into account the material of the “victim” speakers, the material of the wall between your antenna and the speakers, and how much wall is between both. Aerial distance matters only at larger distances. Also, a directional antenna might bleed into other directions given that it is pointed at a slightly RF-reflective surface.

          Powering an amp at that wattage (250), by the way, will probably blow a hole in anyone’s eardrums. I seriously suggest not amplifying anything with more than 4 watts throughput unless you’re willing to accept the consequences of a serious FCC violation.

    any pointers on what you’ve used or to where to get the needed parts? from what i remember linear amp on a cb is not quite legal in some countries … have no idea ’bout romania(my “musical” problems have the same country of origin :))) ). Thanks in advance for any pointers.
