None of this stuff people are saying will help much. Sound will flank any addition you make to the mass of your wall, traveling below and above it. And in reality, your landlord probably doesn't want you hanging sheetrock anyway. If the neighbor can't moderate their behavior, you should think about ending your lease.

 

as anyone who works on music, usually it is your neighbor who is posting this thread.

 

you need to float on rubber. Put new floor and walls isolated with rubber (there is a lot of pieces to isolate sound in special places) after this you put fiberglas, and new walls of plasterboard (isolated with rubber too) . . . at the end you loss about 20 cm in floor and walls, but is nice for isolating.
inside put difusor panels (not reflecting panels) and you can put some vinil an wood on floor.

 

Well, it depends on the neighbor... like how badass he is and stuff...

 

Same situation here.
Concrete walls with no insulation in between suck. You can put a 5 inch rock wool on that wall, that will help significantly but it will also make your room hotter in the summer.

 

Hi @hackerz4life, thank you for the help.

 

The apartment where the neighbor lives is laminate on the floor and nothing on the walls.
If he had a carpet and some shelves on the wall it would also be bearable for me.

Here also live tenants who simply rip open their stereo and sound the apartment block, against it often helps only this:
Here we write to the landlord - keep a noise log and then try to get the neighbor to change his behavior.
Usually he gets a warning - but often you have to sue them in court.

 

sounds like maybe look for a new place?

 

Right you are ? But the residential area is very nice here. Supermarket is nearby and lots of nature !
I'm going to dampen that a little bit and increase my quality of life a little bit.

 

Thanks @CaptainTrams88, for this really useful information.
