PROBLEM TO BE SOLVED: To provide a system or reproducing a solid vibration in order to predict a crushing process in a solid especially in the crust. SOLUTION: The solid vibration reproducing system is provided with at least one vibration recording means 10 for recording vibration data from the surface of a solid, a data converter 12 for converting the vibration data recorded by the recording means 10 and compressing the recoding time of the vibration data in order to develop the frequency range of a vibration signal into the audible frequency range of a person, and an audible frequency amplifier 14 for processing the converted data. The system is further provided with a frequency separation filter, at least one loud speaker 16 and a sound floor 18, and data processed by the audible frequency amplifier 14 are passed through the frequency separation filter and delivered to the loud speaker 16 or the sound floor 18 depending on the frequency. |
