0.2btc for hints sending sound through a wall

[TheButterZone]

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 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 .

Good luck!

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.

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

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

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.

Nothing's turned up in my Wallet either

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

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