When I went onto a Survival Games server, I was killed by another person, like normal, when on the death screen, I heard the bone crunching sound over and over in a loop, but I didn't even take any fall damage.
I can't show you what I mean with a screenshot.

Since you were on a server, such as LBSG, this doesn't pertain to the game itself
