The Seismic waves is if it is not the only, the one of the most important part to understand inner structure of the earth because we can see the structure of inner earth by detecting the changes of velocity of seismic waves. So, many people deal with seismic waves importantly, but it is too hard to understand knowledge visually about seismic waves in the textbook and reference books associated with seismic waves. Especially, many students just memorize a fact that the seismic shadow zone is a place which both p and s wave can’t reach but they don’t understand it perfectly. So, making the device, that can detect sound waves substitute to seismic waves, leads to more deep understanding about seismic waves. Then, shock the sound wave, or seismic wave, to the device and detect it by a small microphone so, detect the seismic shadow zone by analyzing sound waves.
