Yes i had no idea what they were either.
Our close friends son is a music producer and recently moved to a house with a garden room. he wants that as a home studio. To that end sorting out the acoustics is important apparently.
He got a quote for pre made 'traps' and it was eye watering. He read about making your own but he is not practical at all. that is where I come in.
This was the first picture he sent me to show what it was all about
That is a less than ideal setup but showed what traps were - sound absorbent large tubes.
I had no intention of making a thread on this so the pictures are mostly whats app images taken for private messages. It's quiet here on projects so I thought I'd post anyway.
Pipe insulation was ordered. They are all 1200mm long when they are delivered. To try it out 5 of the large diameter with 50mm thick insulation. About 380mm outside dia. they are ordered on inside sizes as they are for pipes.
Seemed fine so 15 more smaller 25mm thick ones ordered. he does have a proper chair btw.
There is no picture of the end cap design i came up with but you can see them in the background here. 12mm MDF circle glued to 18mm spacer block of MDF hot glued to a 25mm polystyrene circle. The poly pushes into the tube and keeps the end central. it also traps the material covering.
The large ones are done as double tubes. They are speaker stands. The lower part is cut to height to locate the speaker at ear level. Above the speaker is a shorter infil unit. I had a lot of wire rope and held it into a hole with a countersunk screw. When the wire is pulled and a screw fitted on top the ends are pulled together and all is secure.
Sneaky shot was taken of yours truly during the outdoor assembly process. nasty stuff glass fibre. You can also see another feature - half the outer foil had to be peeled off to give an absorbent and a reflective side for different applications. It was a 3 man job but I'll leave friend and son out of this.
The covering is stockinette cleaning cloth. It comes on a roll, is tubular, stretchy and is the colour he wanted. The uneven surface of the exposed glass fibre shows through a bit but it seems to function well. 2 layers on everything.
The story so far
Cost so far is about 1/20th of the quote he got. He loves how it works so far and couldn't be more pleased.
Still to do is stands to lift all the smaller tubes to the same height as the speaker units. That has to fit in with his work schedule so not started yet.
There will also be flat absorbent panels hung on back walls. The curtain eyes in that last picture were my way of avoiding a domino disaster where they all fall over. a soft string threaded through so if you knock one it won't go over unless you hit so hard they all move.
