DIY Isolation Platform for CDP

Posted by DragonEars (A) on March 22, 2007 at 00:20:23

DIY (mostly) Isolation Platform
I posted this yesterday as a reply but thought it might have merit as it's own topic.

After some Asylum searches and some research, I decided to try a combination of materials for a mostly DIY isolation platform. For about $200 I am very pleased with the results.

Granite, marble and most stone types ring. Ringing is bad. Glass and most metals also ring. Materials that are acoustically dead are the best. A composite of more than one of these "dead" materials is even better.

The platform (19" x 13") is a composite of 4 "dead" materials in 7 layers. It is plexiglas, butyl rubber, aluminium, mdf, aluminium, butyl rubber, plexiglas.

The composite platform rides on 3 bearing blocks. I purchased commercially made bearing blocks.

On top of the platform are 4 Sorbothane footers. My CDP rides on these. On top of the CDP I have bags of #6 lead shot.

Isolation, damping, and mass loading.

The butyl rubber and aluminium came together as an adhesive sheet called V-MAX, used for vibration and sound damping of ducts and machine covers.

Plexiglas 2 x $12
Butyl rubber and aluminium sheets 2 x $14 plus S&H
3/4" MDF $9 (for 1/4 sheet)
FIM bearing blocks 3 for $89 plus S&H
Sorbothane footers 4 x $6 plus S&H
Lead shot $9
Spray adhesive $7

I did not put sources because I wasn't sure about Asylum rules. If anybody wants sources, just ask and I'll post.

Also very pleased with DIY Bass Tube Traps made from Knauf pipe insulation, 3/4" plywood and cotton quilt batting. Ears and SPL meter readings verified effectiveness.
