What a task, i saw this thread before... Any useful hints so far?

Looks like the OP hasn't logged in in quite awhile. Took all our suggestions and didnt pay anyone anything.

Nothing's turned up in my Wallet either Sad

OP might have tried out a few of our suggestions and come unstuck perhaps?

Regardless, it looks like we're fresh out of ideas.

uyse a glass; like on you drink out of and place it open end to the wall and place the sound device at the closed end and turn it up... it will travel through the glass and the wall at a decibel level up to 15x the input level.

Drill hole, put cable in, seal hole with foam.
Install speaker, and do not make it too loud.

I need a device that can send a loud signal/sound through a concrete wall.
This sound should only be hearead at the other side (receiver side). On the sender side it should not be heared.

I will give a reward of 0.2 BTC for a reference where i can get such a device or how i can build it.

What you are looking for is a subwoofer (or 2).

If you want to really piss off your neighbours get some subwoofers and crank up some gangster rap with heavy 808 drums in it or get some heavy dubstep and shake their fucking walls apart.

I have a 10" subwoofer in my room.. and you can hear it outside easily if cranked up a small amount of volume.

If the goal is to annoy you neighbors (for vengeance purposes) I would choose really high frequency noises. They would pass through a concrete wall without problems and can cause a lot of inconvenience. It's also easier to shield from your own appartement, so the inconvenience to you and your kids will be minimal.
If you get the sound directed right, and you use the idea of the smart switch and IP cameras, it will also be next to impossible to be traced back to you. Choosing a correct frequency is rather hard though, you should look into the frequency-cap for people of certain ages and guess the age of your neighbours Cheesy

.

Good luck!

If there's ever a time when nobody's in your apartment and your neighbors are sleeping, you could get a WiFi smart switch, plug a radio with the bass turned up into it, and turn it on remotely. I would have said a jackhammer or some loud tool, but IDK if there's a smart switch with that much output power.

The trouble with leaving a device in your own home that is left playing loudly (and the neighbors are clued in that you are not home) is that they can then report you for having loud noise.

It's about the flat next to me. The crack addicted neighbours turn their music and TV so loud my children can't sleep well. Talking with them didn't change anything. Police doesn't care.

Even if they did, point IP cameras where the police are likely to be seen, and turn off the WiFi smart switch when they arrive.

If it's something similar to their own noise (and we don't know if it's them talking/arguing/watching TV/Humping/practicing for Choir/Even Praying or Chanting/playing a rusty trombone/MTV...) it might annoy them enough because it's disrupting their own concentration.

Then again, are they elderly? You could get them some headphones hooked up (via WiFi/FM transmitter) to their devices that are making the noise and they can listen at any volume they want and you won't hear a thing.

Thank you guys for your hints!
I will read through them, if one seems good for my purpose, i will try it and if it works, i will send the 0.2BTC.

The purpose should be to send a loud noise to the neighbours that only they can hear.
Or to disturb their speakers.
I can see their Sat antenna. From me to the antenna it is about 8 meters. Maybe i can
kill the lnb with a laser or something?

Your (sick) ideas are welcome.

Actually, now that I think about it... if they have a dog and you send a lot of ultrasonic noise their way, IF they have a dog, the dog will make all the disruptive noise you need :-)

That said, as that you are having trouble with your neighbors... I guess talking to them is out of the question??

Instead of making more noise I would recommend an active noise cancelling device. It does not cost a lot, will solve the problem rather than adding to it and the technology is comparatively less expensive. For additional information look here: https://en.wikipedia.org/wiki/Active_noise_control.

if you complained and they did not change their habits or at least tried to lower the noise, that must be a moron family. Don't fight with them you will start an endless fight and end up same like them, better do what you must do to take care of the loud noise, you will get chance for a revenge sooner or later and you will enjoy it.

I also thought about a woofer but you will hear it in the whole house.

Does anyone know a forum or a site where i can get ideas?

It's about the flat next to me. The crack addicted neighbours turn their music and TV so loud my children can't sleep well. Talking with them didn't change anything. Police doesn't care.

Any other idea? Maybe i can disturb their electronic devices or the satellit signal or something else?

First you need to block out noise via all of the way like wall,window,hollow door and ceiling or floor.now you need think how you will get back to revenge.
I am not sure you have electric box on the wall if you have a box on wall just put a remote or WiFi speaker on the electric switch box as you already soundproof your home so you will not get the noise sound from your speaker.I am not sure you can setup the speaker if you can setup properly I hope it will work for your revenge.

EM fields (from RF to UV) can be harmful for all kinds of living things. So we must be very cautious http://www.instructables.com/howto/jammer/ I hope that everybody understand this.

It's been a while since I was last here, but I do love a good challenge...

Since you are offering fractional bitcoins for hints, here is my suggestion:

Use ultrasound interference. Ultrasound is sound at frequencies above human hearing, so technically, it can be as loud as it needs to be blasted through a transducer... but because it is in the range above human hearing, no matter how loud it is, it shouldn't be heard at least not at the source. Then using the principle of sound from ultrasound which involves interference patterns modulated appropriately, it is possible to direct the sound such that it is basically heard only at the destination. There are companies that have developed the technology described in the wikipedia page:

https://en.wikipedia.org/wiki/Sound_from_ultrasound

You can also Google the details of how sound from ultrasound works and there is also a few discussions on instructables if you want to investigated the DIY route:

The easy and efficient and zero cost way is to jump into the other side of the wall and shout it. Simple.

Sounds very old school Spy Vs Spy stuff. There's a device for sending sound through the ground that can be heard at a distance. (Only trouble is others could hear it).

Parabolic dishes can send sound further and can pick up whispers.

You might have to come clean on what you want it for?

You can connect your smartphone to a bluetooth or WiFi speaker at the other side.
I don't think concrete can block it.

The thing is, OP is trying to send sound back at his neighbors, so he can't exactly set up a bluetooth speaker in their flat. OP doesn't seem to have come online in the past few days, so I'm not sure if the offer is still open.
