I am an independent musician from India. I have access to a room (larger side of ‘small’, decent ratios to begin with), which I want to convert into a home studio for the twin purposes of recording and mixing. Why DIY?
Studio isolation in India is still a nascent industry. There are no cost-efficient ways to isolate “home studios” in the manner and variety available in the US. Hiring professionals here is an expensive affair (much more so than in the US)!
This is the first such DIY project I have undertaken and so..
.. I will be very grateful if you can take a look at the plans which I have laid out below; and give me your opinion on whether there are glaring holes in any of my ideas. I’ve attached sketches to accompany all my explanations. Project aim
: to isolate sound to the maximum possible extent at my home recording studio (acoustic treatment will be done afterwards and is not discussed here). I wish to utilize my existing materials while trying to find a balance between costs and performance; and also have the work I do adhere to restrictions against making any structural changes to the room I have leased (hereby referred to as the ‘Main room’). Sources of sound
: Musical instruments – drums, percussions, electric guitars, bass, choir vocals, and string instruments. Out-to-in
: minimal. It's going to be a quiet neighbourhood (until I move in anyway) Main Room size and nature
16’ (L) X 10’ (W) X 9’ (H). Main room is on lease for flexible period of time. Located on the 1st floor of a large bungalow, the walls are double-brick-layered and about 10 inches thick. This room does not share a wall with any others in the house (S and W walls face outside; N wall with entrance faces staircase; E wall faces an open, common area with multiple washroom stalls.)
The work I do to sufficiently achieve sound isolation will need to be minimally invasive into the structure of the existing building.
There is one other space restriction – a concrete loft built into the East Wall of the room which I do not have the option of modifying. Proposal
: To construct a room within a room by employing various common home studio isolation techniques. DETAILS Main room:
1) I will have sheets of acoustic foam pasted all over the inner walls of the main room.
2) After installing split-Air conditioning, I will have the window fully boarded up with plywood and then covered again with my material ‘A’, unlimited amounts of which I happen to have readily available. Material ‘A’ is: 18 mm thick particle board who’s either face is glued with 5 mm thick plastic foam material (ethylene vinyl acetate or EVA copolymer sheet) and then upholstered with fire resistant fabric.
3) Doors: I will get the surfaces reinforced with absorbent material and the edges treated for isolation by a costly professional. Room-within-room:
1) Step 1: I will have the existing tile floors covered with an impact-resistant acoustic matting material.
2) Step 2: Constructing my “room within room” walls and ceiling.
I will have wooden sole plates installed on the matted floor, around the perimeter of my “room within room”.
Now refer to “ROOM-within-ROOM WALL TYPICAL.png
” where I have sketched out the intended walls’ layers.
I will then have the light-gauge-steel drywall-partition studs installed on these sole plates (shown as LAYER ‘C’ in my sketch). This is intended to be the basic structure of the “room within room”.
3) All around the outer side of this steel structure, I will have plywood boards installed and all gaps sealed with acoustic caulk. This is LAYER ‘B’.
4) To the outer side of this plywood board, I will fix tiles of my material ‘A’ , sealing all gaps with acoustic caulk. Material ‘A’ is, again, 18 mm thick particle board who’s either face is glued with 5 mm thick plastic foam material (ethylene vinyl acetate or EVA copolymer sheet) and then upholstered with fire resistant fabric
. This is my LAYER ‘A’.
5) To the inner side of my steel structure, I will have resilient channels installed, with adequate precautions (shown as LAYER ‘D’ in my sketch).
6) I will then fix my first layer of drywall to this (LAYER 'E'). In the form of 4’ X 8’ panels, with.
7) I will then use GREEN GLUE (I’ve booked 36 X 28 oz tubes of this from Singapore.. waiting to have my plans checked before I go ahead to order) upon the second layer of drywall which I will install on the first layer with its edges in a staggered configuration against the first’s. (LAYER 'F')
8) The door to my “room within room” (at the front) will be treated with acoustic foam and the edges treated by
I hope I have described this in sufficient detail.
I will be grateful for your expertise to gauge the strength of my plans – can I hope to achieve adequate sound isolation with this? Can I eliminate any step of this process? Would you be able to give me suggestions or alternative ideas?
Thank you in advance.
