Seriously the BEST $2 3D printer upgrade!
Why 3D Printing Stack Exchange recommends it
3D Printing Stack Exchange answerers point people to it when asking how to reduce printer noise or ghosting, since it recommends a heavy concrete slab on foam as a cheap fix.

What it is
CNC Kitchen's Stefan shows how placing a concrete paver on a foam mat under a 3D printer cuts printing noise and affects print quality. He tests different print base setups using a ringing test model and explains the difference between a spring and a damper.

I do know about your budget, but I would suggest to buy a silent 3d printer like Prusa i3 mk3 [LINK] which is about $1k. If you decide to tinker your printer instead than take a look on other possibilities: Trinamic drivers Most of the noise is created in motors. Definitely switch to Trinamic stepper motor drivers. I have upgraded from Prusa i3 mk2 to mk3 last weekend and the noise reduction is significant, my estimate is 80-90%. [LINK] Take a look on this awesome blog post and video from Thomas Salanderer about the driver [LINK] . Other good post is on instructables [LINK] . I would not suggest soldering unless you are a skilled hacker. Better option is switch to different board. Prusa i3 m

I got good results by mounting my printer on a concrete paving slab (obviously cleaned and sealed) and placing that on a foam mat. The combination of high mass and flexible mount has substantially reduced ghosting in my prints. Not my idea; I found it on a video on YouTube (linked below). Honestly not sure if this is the best solution from an engineering perspective (I like the idea suggested above of trying to find the resonant frequency) but it's easy, fast and cheap. And as a bonus, it has substantially reduced the noise level of my setup.

Have you tried a concrete tile for garden with foam below it? Check [LINK] The same is on Frequencies at 200+ Hz should not get to the neighbours, the walls and floor will absorb them. Lower frequencies are transmitted much more (see the video). Try that, it's super cheap, and if not enough let us know for further help.

If you hear it from a floor to the other the only thing to change is the base of the printer. Nothing else matters. CNC Kitchen performed measurements especially to avoid noise being transferred to other rooms, the result is that placing the printer not on elastic feet, but on a single slab of concrete which is placed on top of foam is the best solution and reduces the noise significantly.
