During the dataset construction phase, the data is partitioned based on the index supplied by the internal data structure within the file. The mechanical wave detection captured a singular signal pulse spanning a duration of 1638.4 microseconds. In accordance with the instrument's sampling interval of 0.2 microseconds, Python was utilized to transfer signal data in the form of a matrix with dimensions 8192×2.Dataset overviewThis dataset can be very huge (192 GB), so it is compressed in zip format.The total data number in this dataset is summarized in Table: Subdirectory Number of data (Unit: unit) Subdirectory Number of data (Unit: unit) Subdirectory Number of data (Unit: unit) R-S-0-0-0 82930 G-N-1-1-15 59227 G-N-1-5-5 58696 R-C-0-0-0 109217 G-N-1-1-20 90721 G-N-2-1-5 61088 G-I-0-0-0 112596 G-N-1-2-5 53833 G-N-2-1-10 61340 G-N-1-1-5 31814 G-N-1-3-5 57700 G-N-4-1-5 81908 G-N-1-1-10 56403 G-N-1-4-5 77939 Total 995412 <br><b>Acknowledgement</b>Readers are welcome to use this dataset for any type of research.Creator: Zhuoran Tian, Chunjiang ZouDataset correspondence: 220204912@aa.seu.edu.cn, chunjiang.zou@brunel.ac.uk
