Simulation of seismic response to the action of a rain drop

The seismic response to the action of a falling rain drop on the ground is simulated in laboratory. The pulse signal from the output of accelerometers set up near points near the falling of a drop on a hard surface was experimentally recorded. The level is measured, and the spectrum of the vibration signal is analyzed. The theoretical estimates of the level and spectrum of the elastic-wave response agree with the results of experiment. The simulation results can be used to reduce the level of noise caused by precipitation, as well as to study the features of a moving droplet interacting with a hard boundary.
