It is being found that glass ball bounces higher than rubber ball because of its high energy decapitation it is one of the form of energy collision which enables the glass ball to emit huge energy sometimes we hear a huge ringing sound the more it last the greater is the chances of getting higher bounce in the ball surface to jump for a longer period of time provided that it does not break away easily as glass are more likely to be compared to rubber ball.

The bell which is made up of glass or steel more sound is heard compared to rubber due to its high tungstility.
When glass hits a surface then it does not deform readily but if rubber hits a surface then it deforms easily and thus the jumps lower than glass ball.
