Spectral Characterization and Spatiotemporal Variability of the Background Seismic Noise in Italy
Earth and Space Science, 2021 In this study, we assess the spectral characteristics of seismic noise at the sites of the Italian Seismic Network and its spatio‐temporal variability. The evaluation of noise is crucial for the assessment of the detection capability of a seismic network.

Random Noise Attenuation Based on Residual Convolutional Neural Network in Seismic Datasets
IEEE Access, 2020 Seismic random noise attenuation is a key step in seismic data processing. The random seismic data recorded by the detector tends to have strong noise, and this noisy seismic ratio can be seen as a low signal-to-noise ratio (SNR).

Seismic noise in crystal neutron interferometry. [PDF]
J Appl CrystallogrWe are involved in designing, constructing and operating a split-crystal interferometer that uses X-rays and neutrons simultaneously. Neutron interferometers are sensitive to seismic and acoustic noise due to the low speed, low flux and long detection time of thermal neutrons.
