发明名称 Method and a device for reproducing solid body vibrations for the prediction of fracture processes in solid bodies, particularly in the earth crust
摘要 A device for reproducing solid body vibrations for the prediction of fracture processes in a solid body, particularly in the earth crust, is provided with at least one vibration recording means for recording vibrational data from the surface of a solid body, a data converter for converting the vibrational data recorded by the vibration recording means, the data converter compressing the recording time of the vibrational data such that the frequency range of the vibrational signal extends into the audible frequency range of human beings, and an audio amplifier playing the converted data. Further, the device comprises a frequency separating filter, at least one loudspeaker and a soundfloor, the data played by the audio amplifier being passed on to the loudspeaker or the soundfloor via the frequency separating filter in correspondence with the frequencies thereof.
