The earthquake-resistant structural building design is a necessity nowadays. Therefore, the development of earthquake damping device is indispensable. This research focuses on the usage of sand as an additional damping material on a silencer attached to the building structure. The selection of sand as an additional damper is based on the shape of the grain, which could provide additional internal friction between each grain to cause damping. This research is conducted on various types of grains size retained on the sieve analysis with uniform composition within the container and thin plate as oscillating contact area in the sand. The thin plate is connected to a perfectly fixed acrylic-free end tube. The sensor used is a device to gather oscillation data to be processed for the value of damping ratio to be known. The experimental result shows the disproportionate damping ratio (ξ) increment to the increase of contact area (A) and the sand shear angle.
