My friend and I rented an apartment but my gf can sometimes be a little loud. I'm looking for a way to soundproof my room. The only noise will be my gf, normal volume music playing and me raging in video games (no shouting). Below's a rough sketch of the two rooms. beds are probably for certain, there are also two narrow wardrobes and a large L desk i havent placed yet.
I was thinking about getting large wood/plastic panels (light) and stick pyramid shaped acoustic foams on it, then screw the panel to the walls. What do you think?
Also I want to the same thing for the ceiling (ground floor, so floor is not really important) any suggestions on that? No hardcore shit since its an apartment.
with that layout there's not much you can really do
... because ideally you'd want pic related between the sound source and the shared walls filled with books or something and then some acoustic curtains behind it and then some bass traps in the corners, but that isn't really going to work with the door there.

this won't do anything for blocking noise, those are more for making the acoustics in your room nicer
Acoustic foam is NOT for sound insulation.
Its purpose is to attenuate reverb and echo. Increasing accuracy either for recording or playback. Proper sound insulation can be had in one of two ways, the latter more being a function of the first.
Sound is mechanical energy moving through a medium. Typically air. When it moves into a different medium it loses energy. By forcing it to go through various mediums you eventually deaden the sound to background levels. The second method is to just throw a shit ton of mass in there like concrete walls.
In your situation the best and easiest approached solution would be large bookshelves on either side of the wall, preferably units with a back panel to add further materials interfaces. Filling the shelves up with books, clothes and various other sundries will further attenuate transmission.
You could also add a sheet of thick foam behind each bookshelf as well for increased isolation, but two large bookshelves should be just fine
Noise masking is another option. Comercial buildings install speakers in the attic that play white noise that masks conversations in adjacent cubicles or rooms. So you can play music and or run a fan, anything that makes noise that will compete with the noise your trying to cover up.
Record the sound of like 10 - 15 noisy pornos playing over the top of one another so you have a seamless loop of constant moans then play it loud so that your roommate won't know the difference between your girl and the looped track.

attenuation of sound is pretty low for that material, but your right about increasing the distance the sound has to travel through.
I'm a PhD candidate in an ultrasound lab and I agree with everything this guy's saying. This is your best bet, imo
Oh! and to add to that - OP don't expect to eliminate the noise completely with anything that's gonna be a realistic solution. Unfortunately in your case, you may be able to reduce the sound intensity by +30 dB but you're still gonna hear it since our ears are pretty bad-ass at detecting sound over a large dynamic range.
Well, since we went on this road...
(not OP) I like "light" elements of bondage. mostly the rope-tying (nothing where skin starts to turn purple), but I don't like gags. At all. I just don't find it attractive in the least, but that's what 90% of bondage has unfortunately.
Just use eggboxes, they're an extremely cost effective way to soundproof any room.
I covered my bedroom walls in them and my parents haven't said a word about my loud music since.
I've looked into this before and it is fucking expensive. The best way to do it is to build another wall the whole way around the room with soundproof grade sheetrock and insulation. Obviously that is really expensive and you're gonna loose a lot of space.
"Oh! and to add to that - OP don't expect to eliminate the noise completely with anything that's gonna be a realistic solution.

30dB is fucking loads of reduction, he would have to do some serious reconstruction to reduce that much. People always forget that 10db is approximately double/half the loudness. So 30dB is halved, halved again and then halved once more. That's equivalent to eight times quieter.
What you need to do for sound isolation is decouple the rooms. This requires a suspended room inside a room for best results, or in your case some thick rubber inside the walls, between the plasterboard and wooden posts ideally.
This will realistically reduce transmission through the wall, but the next step is to make the room air tight.
Ultimately, this is a lot more work and money than probably worth.
There are 2 types of sound, sound that travels trough air and sound that travels trough walls, both have a different way of being stopped. Sound that travels trough the walls is stopped by mass, meaning you need to add weight to the walls (different weights of walls have different vibrations and theirfor stop the sound from traveling). For sound that travels trough air you need insulation, so something like rockwool. Best way in your case is to build a second wall against the wall separating the 2 rooms. A drywall would be good, but make sure to keep it seperate from the exsisting wall of there would be a leak in sound there. Even add rubber insyuiation between the floor/ceiling and your new wall.
Until you seal off the room you will have very limited improvement. No air can move in or out of your room. More sound will transfer through a 1/4" hole than a whole wall. The tricky thing about sound is it acts differently at different frequencies. If you are pounding the bed, sound will travel through the floor and none of these suggestion will work if you share a common floor, floor joist with your room mate. On high end recording studios they pour the concete floors for the studio and control rooms as separate slabs and they are poured on foam to help isolate the transmission of sound through the floor. Low E on a bass guitar is 41 Hz. The wave length is about 27 feet long. To absorb sound you need about a 1/4 of a wave length of foam or ??, so in the case of a bass guitar you need 7' of insulation. If the foam were 99% absorptive it would only make a 10 db difference to the wave that hit it. The best thing is don't make any noise...LOL
