Rubble impact on a road sign
Dropping a thick branch onto a hard surface, medium impact
Dropping a metal bar onto a soft surface, medium impact
A heavy metal gate squeaking as it opens and closes.
Ball dropped onto a hard surface, medium impact
Slide whistle up and down - wolf whistle
Sound of a ball dropped onto a soft surface, heavy impact
CD jewel case thrown onto pile of CD cases, plastic clatter and rattle
