WTF is this? Numerous ones for sale, here is a great description from one.
"There is a set of machine in the main machine, which is about 1kg and the power is between 10W and 100W. When the machine is powered on, you can see that the machine is vibrating. This is the vibration generated when the machine is running. During operation, the motor in the host will produce violent vibration. The vibration frequency can also be adjusted freely.
The “machine” that does not need to be installed by punching is supported by a telescopic rod to push the main machine on the roof. When the upstairs or downstairs neighbors produce noise, and we cannot solve the problem directly, this is a machine to solve the problem, it is a machine that can produce continuous vibration on the wall, it can play the role of retaliation to the upstairs neighbors and downstairs neighbors.
Are you bothered by the noise of your neighbors? This is an artifact that solves the noise of neighbors very well. Maybe you need it now, so hurry up and buy it."
At first I thought it might somehow absorb the vibrations coming through the ceiling before they can turn back into soundwaves in your room which would have actually been pretty cool and useful.
But, looking at listings on Amazon and other places (which all seem to say about the same thing) and customer reviews… I guess it just makes an annoying hum projected up into your neighbor’s apartment to confuse them and/or express your displeasure? I don’t see where this is going to help for longer than it takes for them to wonder what that annoying hum is. If anything, they’ll probably just turn the television up louder.
Seeing that on the same webpage they also sell this to regrow hair with red light
I can only guess both inventions including the description and the operating manual are designed by AI. I like that it costs $92.28, which they claim is a 7% reduction on the original price of $100.30 Both items probably make great presents.
Well, I for one won’t fall for this obvious scam product and still use my good old broomstick to knock on the ceiling to complain about my neighbors’ noise. It’s the original “reduce neighbor upstairs noise machine”, and it’s eco-friendly and CO2 neutal.
