Silence Neighbours By Transmitting Your Music To Their Speakers

Silence Neighbours By Transmitting Your Music To Their Speakers

If you have a neighbour that’s playing their music too loud, you can get them back by hijacking their speakers with a little DIY project.

Some people are more than a little inconsiderate, and when a friendly note or call to your landlord doesn’t solve the problem, sometimes you need to take matters into your own hands. Evil genius and electrical guru junkyardmessiah over at Reddit came up with this DIY solution:

In deference to XKCD the real way to cause problems with her system is pretty simple. You need a Cheap CB radio, A linear amp, and a bottom loaded CB antenna (easier to build a ground plane for it). See if you can get a good guess where she has her [speakers]set up and get your antenna close as you can to it. You should be able to talk to her THROUGH her stereo system. The amplifier sections are not shielded in these plastic ready made toys and the resulting AM signal will impact it. In my case I ran a continuous 6khz tone from a signal generator which was more than enough to blow it up good. ENJOY!

Essentially, with a few tools, you can transmit your voice, play an annoying tone, or even blast your own music through their speakers — even if their speakers are turned off. If you’re truly evil, you could probably blow out their speakers too, but that could have repercussions. Different states have different legal issues pertaining to these types of devices, too, so check with your area’s laws — if such things concern you — and start plotting. This post details a bit more of what you need and how you can set it up, while this post uses a slightly different method for the same project.

Is it expensive? Yes — the materials can cost up to a hundred dollars or more. But is it pure, cackle-inducing, totally-worth-the-money evil? Most certainly. The instructions aren’t as straightforward as we’d like, but if you have a bit of electronics experience, it shouldn’t be too hard to figure out.

I Feel Bad For This Guy… [Reddit]


  • This is awesome thankyou, a bit too late though for us! We just moved house because our loser neighbours used to play crap loud music really loud all the time!

  • You’re making articles now from comments on Reddit? This is just getting ridiculous. Have you even tested this to see if it works? How about actually investigating on whether or not this is real or just another Internet troll having a laugh? I know this site is dodgy at times, but this really takes the cake. A++ quality Gwaker right there!

    • It works. I was a teen the CB Craze swept America. I had two co-phased antennas and a 150W amp connected to my CB and I could talk dirty over the speker system of a local resturant, raise certain garage doors, change channels on certain peoples TV’s and extinguish street lights, All this just by keying the mic. What can I say, 17 year olds are easily amused.

  • This will make the problem worse. Ask nicely twice then make a complaint to the police. Although you do not need to apply for a CB licence in Australia, they are still operated under a class license and radiocoms act overseen by ACMA. Connecting linear amps is not allowed as is using the device to cause interference or harrasment. Although this a little tongue-in-cheek and I really doubt that anyone would go to this much trouble or get busted, it’s worth knowing the rules and laws as revenge can turn nasty very quickly.

      • I am at wits end. I have had some rotten neighbors in the past 18 years living next to me. I asked nicely when I told them their stereo is bouncing stuff off of my walls. The sound is projected towards my bedroom/bath wall. I hate this Mexican music with words sooo loud and in Spanish. I am just a regular white woman and the loud trumbones, bass guitar! I cant even watch tv in my living room! They made the old garage a theater with their stupid flea market shit! I don’t mind music in any language with a certain degree of volume to it. But when a person such as myself does not speak anything but English. Its beyond rude. I am a good neighbor. I want to scream!

  • Assuming its legit, it *IS* a comment from reddit.

    I heard ferrite beads stop interference from cb being picked up on speakers. I wouldn’t be surprised if it worked to stop this too.

  • This is legit. I have been talking on radios for 30 years now. Radio waves are just alternating currents at different frequencies. Anyone who knows anything about electronics, or mechanics, knows that magnetic fields collapsing will induce a current onto anything conductive within their reach. That’s how the coil in your gasoline engine ignition works. You can make speakers boom with your voice, shut tv’s down, turn on and off touch lamps, and even light up florescent bulbs by holding them in your hand. People have even heard radio stations over their braces in their mouth. This theory is how all AC step up and step down transformers work. Have you seen those wireless charging pads for cell phones and other devices? That’s how they work. Back in the day before good shielded electronics, drive through windows were very fun to screw with. You could say anything you wanted to the employee taking the order. This practice, although fun, is illegal. The maximum transmit power in the US is limited to 4 watts. You need much than 4 watts to be effective at bleeding over to other devices. Excellent article boys. Keep up the good work.

    • to WHIPP, actually the EM shielding for your speakers is there so the magnets in them won’t mess with old CRT monitors and TVs…….the wattage required to do in this discussion will punch right through the aluminum foil “shields” around your magnets……….if it aint in a FULL faraday cage, its gonna be messed with from that much RF……….take it for what its worth……….sorry for the bad news, but thats all your EM shielding is there for, just to stop the color blossoms on old CRT stuff which is getting rarer and rarer with the advent of cheap LCD screens

  • @Pat: I can tell you, it’ll work on a car, if you can get strong enough Amp, close enough to the car!
    I was working radio towers, on a Georgia mountain top & my trucks front speakers just started playing what it was picking up from the station, & it wasn’t even turned on!
    granted I had self installed a pair of Component speakers that had a cross-over coil between the tweeter & the Mid so, it gave it a greater point of induction.

  • The longer the offenders speaker wire are. the better your interference set-up will work and such offenders DO have long speaker wires all over there dwelling.

  • Word of warning though………..when producing this much RF energy in that frequency band your going to be in a harmful RF field……….your probably going to need something in the 1KW range, put that in your apartment and nothing good will come of it…………the band is the upper HF band around 30Mhz, that much power in that frequency range can affect your eyes, your fingers, your arms, and your testicles…….basically anything long enough to be an antenna will absorb the power as well, that includes YOUR wiring, if you have any cheaply built electronics without good isolation in the cords POOF they’re gonna be gone too……………..that being all said……….it is FUN as all get out to do…….and for you nay sayers…….YES it absolutely works like a charm, so until youve actually done it, then don’t try to sound educated when your not……….I AM educated, united states navy ET specializing in HF communications, licensed Ham operator, currently working in telecommunications…….been in to radio for over 35 years…… yeah, i DO know what I’m talking about

  • I’m pretty sure that using a linear amplifier with a CB radio is somewhat illegal since those have a power cap. Would a 10 meter radio work since the wavelength is only a meter shorter than CB? (Not that I, a licensed ham, would abuse my powers. But just in case, I’ll chalk the noise up as radio interference and let FCC article 15 save my booty. Blow their speaker, and bam, interference issue resolved.)

  • My CB was so powerful that I used to be able to cycle through my next door neighbors “Touch-lamp” brightnesses every time I “keyed-up”. Wattage is fun

  • hi all, i have the same prob as a lot of you out there…noisy inconsidering shit music playing neighbours!!! if i go down the route of cb/linear amp set up,what is the best but cheapest option i should go for?

  • I’ve read this before and I’m 100% sure I want to go with this as I have a neighbor who blasts his radio constantly. I live in a townhouse and that doesn’t help matters. That said I’m a CB / Ham noob. What do I have to do, where can I go to get the parts to make this on the cheap (Cheap as possible not as in a few dollars.) I already know where their radio is as I’ve been in the house to try and help them lower the noise but they are at the point where they don’t care and I’m at the point where I’m about to go postal…… and I rather not.

  • i already knew about this.. but wouldn’t a linear amp be a bit too much for say an apartment building with very thin walls/floors.. wouldn’t a base station CB be more than enough pain?

    was wondering about that…. considering i used to have linear amps (scott-ham) and i’m sure that i’d blow everything out, all the neighbors, my junk and the windows. ?

    just a curiosity, i mean this person is right next door.. the walls maybe 8″ between us with nothing really filtering anything not even the cold. i can hear conversations between the floors they’re too thin.

    so, my question, again: i wouldn’t need that amp would i?

    ?! (sweating.)

    i’d probably start migrating transmissions into the adjacent building, wouldn’t i?
