Hi guys.Can anyone tell me if they are using this material for stand filler,how they think it compares to sand or shot & what type of filler to use(Horticulture Perlite or Granulated Masonary Fill)?Thanks much,take care...
Perlite is too lightweight to have much effect. You're better off using something like clay granules (kitty litter) if you want to steer clear of sand or lead shot.
I've thought about this. To damp ringing in a metal structure, you need mass applied to the structure. Lightweight materials simply won't have much effect on this. Gravel, because of the space between granules, is lighter than sand but does very effectively damp the ringing. Hence my solution.
