Hello all.
I`ve started to build my new HT, and i`m planning to build it soundproof.
The room will be supplied with traps an diffusors.
I hope to build a great room with great sound and no need for robbing my bank.
This was my old HT.

The last picture, the room is empty, only the concrete floor and walls.
Almost ready to start the build.
I`ll post pics and if anyone have any tips i`ll be very grateful.:hail:

 

[lglura]

Thanks again Ted, this is realy helpful. I`ll share my plans in this thread.
I think i`ll have a great sounding room thanks to you all.
The room has two doors, i`ve moved one.

One more question, how do i install the wall studs to the concrete wall.
Are resilient clips an option.:help:

 

[lglura]

Wall studs would not contact concrete wall = decoupled

There are two types of clips. One decouples the frames wall from the joists overhead. This is the DC-04 clip.

The other clip you may be more familiar with is the sound isolation clips like the PAC RSIC-1 or WhisperClip. These isolate the drywall from the stud wall

If the wall itself is separated from the concrete you would benefit from the DC-04s but not the Sound isolation clips

Thanks Ted.
The wall itself is separated from the concrete wall, the DC-4 looks great, how many clips should i use in the wall.

Do not need two windows, blind both. Now i have better lightcontrol.
Almost ready to start the build.

Hi guys.
My biggest problem is to keep the sound in. I`m live in a quiet neighbor relationship and i am the neighbors nightmare:hush:.
The reason why i am building this soundproof HT is when i tested one Tubesub!!!( i have two) my wife open the door and screaming that either i had to turn down the sound or do i need to glue the plates to the shelves and buy a kidney belt:rofl:.
I have good plans for the room (thanks Ted for your heads up) the biggest problem is to keep the vertikal height. I will describe later

 

[lglura]

Wow guys, i think i `ll describe the build soon. i need a simple program to sketch it.
I`ll build the room airtight with no leaks, floating ceiling on floating walls attached with resilient clips to the concrete and a floating floor inside the wall. I`ll have two airtight doors. There is no weak point exept to little vertical height ( i hope). The acoustic treatment will be carried out when the room is done.

Keep in mind you're still going to hear subs.

I can live it as long as my wife is happyaddle: and i can watch movies without any limitations:R

 

[lglura]

What can I say, I am very grateful for all the answers.:hail::hail::hail:
I am not a beginner, and certainly not an expert, so please contribute, even if it flies over my head.
I would agree, this is very educational.

 

[lglura]

When these two doors are closed, are they side by side or is there an airlock created?​

It will be an airlock between the doors, indipendent ceiling joist as in the article.
I plan to build a floating floor for insulation and decoupling.
I shall try to describe with a sketch before the nails and screws fly

 

[lglura]

I know it but I need to isolate, it is cold in Norway

 

[lglura]

You're below ground? Or no? Cold in the states and canada as well but a few feet below ground it's all same temp all year. Small point, as many do this for thermal comfort nonetheless.

Have not thought of this, the floor in the room is two feet below ground.
Possible a thick carpet is solution,I get two inches extra ceiling and the height is 230 cm.

 

[lglura]

Volum reduction or sub across the couch, sorry but it is not an option.:nono:
I begin to understand how to build the room, i will describe it when I'm back from vacation, traveling tomorrow.
lgl:wave:

 

[lglura]

You cannot turn down the volume?


It's your hearing your talking about losing...not if, but when.

Appreciate your concern Space, but the volum is not that loud.
:heehee:lgl

 

[lglura]

I would not take up valuable headroom for that floor.

Hi Ted.
How much difference will 7 cm represent if I lower the floor, the room is 730x330x223 cm.

[lglura]

So I assume the Holiday went OK?

Yeah Ted, was a trip in France and the holiday went OK, and now i am ready to continue with my build.

[lglura]

Are you suggesting removing the concrete floor and re-pouring? I'm confused... sorry.

7cm isn't a lot of height to gain considering the work involved. Again, I'm probably misunderstanding

Sorry Ted, but I have problems to explain me properly, will try to be clearer.
I`m not removing the concrete floor and no re-pouring. The height between the concrete floor and roof beams are 230 cm. Between this I will build floating ceiling and floor, and the space is limited.

Hello again. Thanks for all the feedback in this thread,
have finally realized that it is not possible to build the room completely soundproof.
Thanks to all the feedback I now know how to build the room.
I will build it as solid as it is possible within the limited space I have, walls and ceiling get 2x 1/2 " drywall and 1x 1/2" MDF and green glue between the layers. I come back with pictures to describe the build:bigsmile:

 

[lglura]

Looking forward to the pictures!! Good luck and keep us informed. Out of curiosity (maybe I missed it in the thread), why 1/2" drywall, why 1 layer of MDF, and what will the sandwich look like (dry W, dry W, MDF? or MDF in the middle?).

Thanks

Hi patshesj. It is drywall/drywall and MDF as the inner wall plate and i`ll use 1/2 " because it is the cheapest solution, 5/8" comes only in fire-plate design.
This is the type of MDF wall plates I`ll use
