Abstract 

To improve understanding of the transmission of energy in granular materials, we propose to carry out laboratory attenuation experiments on dry gravel through the administration of pulses and signals. With the current conflict between the jolt and seismic reverberation attenuation models in the literature we aim to differentiate between the two models in our regime by making a precise measurement of attenuation. 

Additionally, by making attenuation measurements of materials with various densities and grain sizes we can better understand how seismic impacts would affect granular bodies, such as rubble-pile asteroids
