Speech extraction from vibration signals based on deep learning. [PDF]

open access: yesPLoS ONE, 2023
Extracting speech information from vibration response signals is a typical system identification problem, and the traditional method is too sensitive to deviations such as model parameters, noise, boundary conditions, and position.

A parameter adaptive EEFO VMD method to mitigate noise and trend interference of blast vibration signals [PDF]

open access: yesScientific Reports
Blasting vibration signals are often contaminated by trend terms and noise, stemming from environments, and instrument errors. This contamination hinders subsequent signal processing and analysis.
