At the end of last year I set about making these acoustic traps for the studio. The work consisted of making a wooden frames to house thick rockwool slabs covered in hessian.
They are there to absorb sound waves and prevent them from bouncing around the room. Big thanks should go to Michael Armstrong from http://www.afiddesign.co.uk/ for helping cut the lengths of wood precisely with his massive circular saw – if I had done it myself I am pretty sure they wouldn’t look quite as symmetrical as they do.
You can see the end result – three of them are hanging on the wall here behind the speakers – I have a couple more to do as well as a larger trap to hang from the ceiling but the sound is already loads better – much tighter top end and a lovely rounded bottom.
