Over lest the last couple of weeks I’ve written up about how I designed and constructed the acoustic treatment for my home studio. Last week I even put together a short video about the difference that it makes.
Today I’m going to give you a quick rundown on how I fixed these panels to the walls and ceiling of my room and the overall costs involved in doing such a project.
Mounting
Here are a couple of pics showing you how I fixed my acoustic panels to the ceiling of my room.
As I stated last week, I have an i-beam running down the centre of my studio. I fashioned some brackets out of 6mm threaded rod and used stiff wire to hang the panels. In your studio, you might need to screw hooks or eyelets into your ceiling to hang the panels.
The panels on the walls were then hung with fishing line from the upper skirting board. You can then use stiff foam or leftover wood to displace the panels about 100mm from the walls.
The bass traps were simply wedged into the corners. My ceilings are 2200mm high to I made my panels to fit snuggly.
Costs
This is a breakdown of the overall costs of the project. All prices are in Australian dollars and the best prices were sought where possible.
The overall project cost about $500 but this is assuming that you have access to the required tools: saw, angle grinder, staple gun, drill and scissors.
From these prices, you can estimate that each floor to ceiling bass trap cost about $110 to construct and each 600mm x1200mm acoustic panel cost about $44 to construct.
Doing a quick search on the internet, I have found that an equivalent commercial 600 x1200mm panel costs about $200US. If you’ve got the time and you’ve got a good DIY attitude, I would highly recommend building your own panels.
I hope you’ve enjoyed these articles on DIY acoustic treatment. Feel free to leave a comment or shoot me an email about your own projects!
Okay, last week I went through the concept and design process and this week I’ll be running through the construction process.
Frames
As I said last week, all of the frames are made from 18mm x 38mm pine. It’s cheap, strong enough and easy to work with. To make it even easier to get square corners I made up a little jig with some scrap pieces of wood.
You can also see how each corner was fastened in this picture.
I then went through the process of rigging up the frames in my room: 1. to check how they would all fit in and 2. as it was a lot easier to hold and fasten light wooden frames rather than complete acoustic panels.
As you can see, I am lucky enough in my room to have an i-beam running down the centre of the studio which makes it super easy to fix the panels without having to drill holes. The panels on the ceiling were hung with stiff wire (roughly 1.5mm dia.).
I then took all of the frames back outside to fix the backing fabric. You can see that I used staples about every 100mm to hold the fabric to the inside of the frames.
Cutting Insulation
The next job was to cut the insulation. Tontine Acoustisorb 3 is fairly easy to handle but rather difficult to cut. I took the hint from Timothy Allan when he built his acoustic panels and decided to use an angle grinder with a cutting blade to cut the sheets. I first attempted with scissors first but quickly found that my scissors would become blunt after cutting through about half a metre. So, I used a pen to draw up the straight cuts on the sheets and then ran the angle grinder through them.
One entire pack (three 1200x2400 sheets) was used to make the two corner bass traps and the other pack was used to make the six smaller acoustic panels. This picture shows the insulation on the wooden frame.
Finishing
Before wrapping the panels in fabric I stapled the first sheet of insulation to the wooden frames. This would help prevent the insulation from sliding down the panels over time.
In this picture you can see how the fabric is then wrapped around the insulation and fastened to the back of the frames with staples. I would always fasten one long side of the the panels and then the opposite side to ensure that the fabric was pulled tight. For some of the panels I had fabric with stripes so this technique would ensure that the lines were aligned to the frame. Here is one finished floor to ceiling bass trap.
In The Studio
Here they are, finally in the studio. The floor to ceiling bass traps were just large enough to wedge in the corners and didn’t require andy fastening. The panels on the walls are just propped up for the moment but will be fixed with fishing line to the upper skirting board shortly. I also have one panel that is hung directly behind the mixing position that you can’t see in these pics.
The Verdict
Incredible. It is amazing the difference this acoustic treatment does. Flutter echoes are no longer an issue, the bass response of the room is so much tighter and stereo imaging is pristine. I can tell that is going to be a pleasure to mix in this room. If I can get a hold of an acoustics measuring kit I’ll run some tests but next week I’ll show you guys a video that I am putting together with some before and after audio samples. Stay tuned.
