Acoustic panels for sound studio, by Michael

To prevent early reflections in a studio, you can install acoustic panels. You can easily make this by making a wooden frame, filling it with rockwool and then sealing the whole with an air-permeable fabric such as jute.

Based on the size of the rockwool boards (100.0 cm x 60.0 cm x 7.0 cm) that must fit exactly in the wooden frame, I made a frame of MDF. The MDF planks were 1.8cm thick, so you arrive at an outer size of 103.6cm x 63.6cm x 14cm. I wanted to have at least 2 rockwool sheets of 7.0 cm thick each on top of each other, so 14.0 cm deep. First you assemble the MDF frame using metal corner anchors. Then cut a piece of burlap to size and use a staple gun to close one side. Then place the rockwool plates (2 pieces) in the wooden frame. Then you also close the back and fold the top and bottom in a nice way. Just like wrapping a present. With some hanging material you place them on the wall and/or ceiling and you're done :)
