Distributed acoustic sensing is shown to cancel seismometer noise with a residual factor near 0.11 at 20 Hz, comparable to geophone arrays, though the evaluation appears to use in-sample Wiener filtering.

Distributed Acoustic Sensing for Environmental Monitoring, and Newtonian Noise Mitigation:Comparable Sensitivity to Seismometers
Distributed acoustic sensing is shown to cancel seismometer noise with a residual factor near 0.11 at 20 Hz, comparable to geophone arrays, though the evaluation appears to use in-sample Wiener filtering.
