DIY: How to quiet down that noisy equipment rack

rackDIY Project – Rack issues


Take a few seconds and DIY fix some of the common problems with using equipment racks!

Not too many people think about their equipment racks, but many of us use them.  Usually it’s something like what you see to the right – the great, sturdy, utilitarian box.  Unfortunately, there are a couple inherent problems with these:

  • Ringing – The metal resonates causing a ringing effect – may be masked by program material.
  • Reflections – many times your rack is near sound sources causing reflections off the hard surfaces.
  • Noise – Fans and other devices in the rack can make noises that are disruptive to recording.

Here are a few DIY fixes for these common problems.

  • Composite foam with adhesive backing is perfect for stopping the ringing of filler panels.
  • Use some Composite Foam to line your trays, drawers and shelves to keep items from rattling around inside the case.
  • Make a temporary cover for the front and back with BlockAid® sound barrier with minimal ventilation cut-outs to use during takes if rack-borne noise is problematic.
