3. Killing control room ceiling and floor reflection­s

More MelaTech or similar, but this time in chunky shapes. Wherever you end up sourcing your open-cell melamine foam, it’s worth buying it ready-cut. A steady hand and a breadknife will get the job done, but unless your going to cover it, it’s definitely better to get it pre-shaped. Shapes like this one are great for removing floor-to-ceiling flutters and tightening the stereo image. Here’s how to attach them…

Use 200x100mm aluminium plates as your magnetic fixings. Again, Evo-Stik will do the job, but for the very best join, use a glue gun and then a hot iron on the plate for a minute or two, and leave to dry overnight. If your ceiling is high enough, use a long screw on the magnet, making a 200mm gap between the MelaTech and the ceiling. This increases efficacy, as sound hits the MelaTech, goes to the ceiling, and then goes back through the MelaTech again.

Use a plasterboa­rd fixing like this one to screw a circular neodymium magnet to the ceiling. This is by far the easiest way of getting your foam up and down, and if you accidental­ly knock it with something, it’ll move rather than get holed. The magnets also enable positional adjustment, of course, so you can easily move your shapes next door into your ad-hoc vocal booth!

Last but not least, the flooring. If possible, use a thick underlay and wool twist carpet. As well as softening the room, it’ll be very comfy! Add to that an extra rug underneath the chair and you’ll have pretty much eliminated floor-to-ceiling problems. The general rule with home rooms is that they’re never great acoustical­ly, so the idea is to kill the reflection­s completely.
