What's a cheap, effective, and non-permenant way to soundproof a room?
I was thinking of gluing foam to plastic poster sheets and just nailing them to the walls.
Like...a bunch of them side by side...
You can never completely soundproof a room unless you go to complete extremes and make a dedicated purpose built sound room.
Your most effective solution is to use closed cell foam, the one that looks spikey. You can wrap it in a grass or cloth material to make it look less ugly. It'll dampen the sound from the inside, but will never make a soundproof room.
Again, my biggest gripe about /diy/ is nobody tells you what the situation is or what their goal is.
I want to make a little soundproof room in my basement for voice acting.
I just want a room where I can scream at the top of my lungs in cartoonish voices.
I also like playing and singing on guitar.
I just don't want neighbours walking around on their property then all the sudden hear bad impressions of the Mark Hamil's joker and think "wow I live next to a fucken dweeb".
>Without tearing apart the walls, you need some lead filled curtains or such.
Fine, I'll help.
This guy has it right.
Best and cheapest way to to deaden sound in a room is to add mass.
Ideally you would add mass to all the walls, ceiling, and floor.
Since you will no doubt want to do this for cheap. Carpet throw some cheap carpet on the floor. It will absorb a lot of the sound.
Hang heavy curtains or fabrics around the parameter of the room. Blankets can be had pretty cheap at thrift stores. The thicker the better.
For the ceiling, drywall is your best bet but failing that you could also use fabric here. Staple it up.
The issue you might have with this is that it will deaden the sound but since you're voice acting, it might make it sound like total shit too.
I had the idea of tacking fabric sheets to the ceiling, from their corners, which are allowed to "dome" down. Then I'd fill the dome with balls of scrunched up newspaper or something, to absorb some kinetic energy.
Is this a good idea or a crap one?
Consider insulating a closet.
A rapper friend of mine records amazing vocals in a closet packed with clothes and blankets piled up on the door.
I'm sure the occasional siren or other loud, sharp noise interrupts occasionally, but I can't tell the difference between what he records at home and what he does in a real iso booth.
>wants to scream
>also nobody can hear him scream
A friend of mine is a professional audio engineer. His solution to this problem was to buy a small prefab shed, which he soundproofed and assembled in his basement to create a soundproof booth.
First, Adding shit like blankets and bullshit are just going to dry up any reflections in the room otherwise creating a "dead stage". This is not going to help from his neighbors hearing OPs pleb bullshit. Instead it will create a good recording environment. What OP needs is a sound barrier like those used for drummers. Its essentially a tight little box made up of plexi glass and insulated by foam. This box will surround you and its essentially limiting the amount of air that is affected by your sound waves thus making your bullshit not audible to your neighbors.
foam wont do shit for soundproofing. It makes the internal acoustics different, but from outside it will make very little difference.
hang heavy blankets from the walls, covering as much of the walls as possible in heavy blankets. this will have somewhat significant impact when listening from outside but FAR from reasonable soundproofing.
only real option for legit soundproofing is room within a room.
acoustic treatment is not soundproofing. eggcrate foam is shitty acoustic treatment. wedge foam is good acoustic treatment. both are shit soundproofing options
if you'r not likely to touch the walls, fiberglass insulation will help, and is easy to cover every inch of wall space
packingfoam and eggcartons is the oldschool method.
doesn't do much for bass.
but more importantly they kill reverb.
my buddy rented a band room once and he started to tear some down because the room was too dead.
sound died instantly, like speaking in mid air.
