Vibration isolation effects of barriers filled with ceramsite and Sand …
Therefore, the influence of the ceramsite-sand mix ratio in volume on the vibration isolation effect is studied by the numerical method. Without loss of generality, four typical mix ratios (0%, 30%, 60%, and ) are chosen for a continuous barrier with the dimension of 6 m × 1.5 m × 0.7 m. In the finite element model, Young's modulus ...

vibration damping with Sand | OCAU Forums
Whats the best sand to use for vibration damping??? (and adding weight) I was going to use beach sand, but have read that river sand would be better. So which should I use? FWIW, the sand will be used in a pair of speaker stands. Last edited: Nov 29, 2003. Shintaro, Nov 29, 2003 #1. Tommy2toes Member. Joined: Jul 16, 2002
