Hacker Uses Raspberry Pi and AI To Block Noisy Neighbor's Music (tomshardware.com) 93

Maker Roni Bandini developed a Raspberry Pi project to address his neighbors' loud reggaeton music by creating an AI-driven system that distorts audio on nearby Bluetooth speakers when reggaeton is detected. Tom's Hardware reports: Powering this Bluetooth jamming device is a Raspberry Pi 3 B+. It's connected to a DFRobot OLED display panel, which has a resolution of 128 x 32px. Audio is observed using a USB microphone, while a push button handles when the system will perform a check to listen for any potential reggaeton. According to Bandini, the Pi is running Raspberry Pi OS. The AI system driving the machine learning aspects of the design is Edge Impulse. With this, Bandini was able to train the Pi to listen for music and more specifically identify whether the song playing is classifiable as reggaeton or not. The official project page is available at Hackster.

        You don't necessarily need to. Plenty of cars are networked, so you just need to hack them, and they often have miserable computer security. There was even a famous hack that allowed someone to take over a car's computer systems through their wireless tire pressure sensors.

      Some kid was going past our house every evening on his scooter with the muffler taken off. It's illegal but the police aren't all that interested unless you hand them the evidence on a plate.

      I was thinking about setting up a Raspberry Pi with microphone, triggered to record video of him when a certain volume threshold was exceeded... But in the end I noticed that he always comes around 20:10, presumably after finishing his evening job, so I just stood out there a couple of times and made a video on my phone

    Neither the article or summary could be assed to explain how the device interferes with the Bluetooth speaker.

The neighbor could also switch to a wired speaker, that's what I would do. Those are less likely to be battery powered, hence louder.

      In the 90s I remember a guy who built a similar anti-loud-music device but using different principles. In apartments his neighbor had his speakers directly against the common wall. So he got some strong electro-magnets, connected them to a wave generator and an amplifier, and then he'd just send various 'sounds' through it. No sound would come out of his, but the magnetic coupling would be picked up on the other side and strongly interfere with the music. I remember him mentioning various tests with white noise, sine wave, grating square waves and very loud impulses...

        The easiest way, albeit far less surreptitious, is to replay the sound back to them with a 0.5 second delay. This has the added advantage of working on people singing or playing an acoustic instrument.

      • I once tested this idea with a large coil I placed against the ceiling, hoping that my upstairs neighbour's equipment would be caught within the near field. I then played some horrible schlager through the coil. Unfortunately, the only effect I got was on my side, with a large metal rack vibrating to the tune.
    • So a Denial of Service utilizing the EM spectrum. I am betting that the FCC has some rule somewhere that they could use to prosecute this guy. This is something I would have kept private.

      • In this case, it's near-field, so I don't think so.
        He's disrupting the big magnets in the speakers with his big magnets. There is no spectrum.
    • That's too bad. It would have been nicer if it were able to turn down the volume on the speakers.
  • Since all my sound systems are wired. At most WiFi, and easyly replaced by Eth via G.hn or Homeplug (if needed be). So, no way his Trick stops my music ;-)

          In Argentina, I doubt the cops really give a shit.

          A quick read of that is that it applies to radio stations. Looks like that organisations targets radio stations that aren't paying for the correct type of license. Less of an FCC, more of a IRS for radio stations and telcos.

      The chance of a regular Joe or Joelynn figuring out what's happening and reporting it is unlikely. If caught, just say you were learning electronics via experiments and didn't know they interfered. Have lots of "junk parts" and how-to manuals laying around to look student-y.

      I doubt the FCC would put much effort on deep inspections for a small domestic complaint, just tell you to "knock it off", and at worst confiscate your gizmos and lock them up next to the Ark of the Convenient to be thrown out in 50 yea

      • So you would like to get locked up for perjury instead of a civil fine and a court order to knock it off?

        Nobody that writes code to produce a denial-of-service attack that directly violates FCC Part 15 [ecfr.gov] that only starts when a particular genre of music plays is going to be able to claim ignorance of the effects. And the code, and these news articles talking about what it's used for and how it's used would definitely come up in an investigation.

      • You're right. The FCC would most likely only get interested when this attack is used more than a few times.

        But when they get interested, it may be expensive.

      • confiscate your gizmos and lock them up next to the Ark of the Convenient to be thrown out in 50 years.

        Ark of the Convenient? Is that the smaller, lighter version of the Ark of the Covenant? ;)

    • Nope. The project doesn't interfere with anything under FCC control. It abuses a factor of Bluetooth while also being completely compliant with RF regulations.

      • Yes, it does.
        It communicates on unlicensed spectrum.
        Intentional interference with another unlicensed device is flat out illegal.

      Unfortunately it's impossible. Noise cancellation only works when it happens right in or next to your ear. In a room where the sound is transmitted through many different solid objects like walls, and bounces all over the place, you can't just use a speaker to block it.

      Headphones would work, but wouldn't be able to stop all the rattling from the bass.

      Often though you don't need to hack anything, just connect to the speaker yourself using the default PIN code and turn the volume down.

        Partly wrong. There are available systems now that are installed all around outdoors concert venues to attenuate the lower boom-boom frequencies for the neighborhood. They need to be calibrated an positioned precisely but they work.

      I've long wondered if building some noise cancellation in my front yard would be feasible. Morons with exhaust-less bikes or souped-up cars pass multiple times a minute when the weather is good... I know this tech already exists for concert venues outdoors. I've done some acoustic research software in the 90s so I should get to it... And I wonder if the reverse is possible: above a certain noise threshold, use several speakers to generate an in-phase sound directed at the origin. If a resonance can be built

      "I think that there are certain crimes which the law cannot touch and which, therefore, to some extend, justify private revenge."

      Revenge is the worse possible way to deal with crimes. And no, justice as a community service is not very good to deal with minor neighbourhood issues like loud music. People could be responsible socially educated adults or at least try to and learn how to peacefully deal with those kind of minor annoyances rather than calling the police or producing counter annoyances and vengeance.

      • Minor annoyances? Clearly you've never lived anywhere close to an ignorant prick who plays unbearably loud music at all times of day and night, witout respect for your need for sleep. We're not talking about a random night. This goes on repeateadly for weeks, months, years. Some people just have it coming.
