ACOUSTIC DEVICE FOR REDUCING CABLE WAVE INDUCED SEISMIC NOISES

摘要

A distributed acoustic sensing cable including an optical fiber waveguide configured to provide light signal transmission and an acoustic device coupled to the optical fiber waveguide and configured to provide acoustic signal transmission. The acoustic device includes a polymer composite having reinforced fibers embedded therein. The polymer composite having acoustic waveguides for attenuating undesirable acoustic waves propagating along the distributed acoustic sensing cable and optical fibers embedded within the polymer composite that extend along an axial length of the acoustic device that facilitate the light signal transmission.
