# Does the surface roughness play any role in shock absorbing?

Consider a mass of about $$130 \pm 10$$ kg, falls from height, let say $$2.5$$ m. In order to dampen the vibration and sound, I use silencer or drop pads. I was wondering if introducing the macroscopic projections, helps to reduce the thickness of the shock absorber in comparison to the classic flat surface shock absorbers.

After reading Kamran's answer: I think the impact energy results in transversal deformation of the projected surface, that is in contrast to the vertical compression of the flat surface. So there would be less energy transmitted to the floor.
