Seismic noise in South China Sea: High-quality time-frequency analysis from 0.01 to 125 Hz

Open Access Peer Reviewed Research Article 2024

Journal of the Acoustical Society of America

Liu, L., Guo,Y., Li, F., Wang, S.,Zhang, F. ,Zhang, Y.,Yang, J., Qiu, Y., Liang, Q.

An efficient and precise time-frequency analysis method for real-time ocean bottom seismometer (RTOBS) data in the South China Sea (SCS) is presented. Method involved temporal segmentation, unique frequency octaves, and Fourier transforms to generate power spectral density. The method demonstrates superior precision, computational efficiency, and full bandwidth.
