-  Having a soft granite suspension could greatly improve the sensitivity the ground motion and thus the level of sample vibration if it is found that ground motion is the limiting factor.
+  Having a soft granite suspension greatly decreases the sensitivity the ground motion.
+  Also, it does not affect much the sensitivity to stage vibration and direct forces.
+  Thus the level of sample vibration can be reduced by using a soft granite suspension if it is found that ground motion is the limiting factor.
