Abstract: At least some illustrative embodiments are apparatus including a tube having a wall defining an interior volume, first and second optical fibers disposed within the interior volume and the first and second optical fibers joined at a first splice. Also included are third and fourth optical fibers disposed within the interior volume, the third and fourth optical fibers joined at a second splice. The first splice and the second splice have an axially spaced-apart relationship within the interior volume of the tube.

Abstract: A method. In one embodiment there is provided a method in which a direction from a sensor position to a noise source is determined. A coordinate rotation is applied to a first set of signal values, wherein each signal value of the first set of signal values is based on an output of a corresponding component of a three-component particle motion sensor at the sensor position. The applying generates a rotated set of signal values. The coordinate rotation comprises a coordinate rotation transforming a first set of coordinate axes to a second set of coordinate axes, wherein the first set of coordinate axes has each coordinate axis aligned with a corresponding component of the three-component particle motion sensor at the sensor position, and the second set of coordinate axes comprises a first axis pointed in a direction opposite the direction from the sensor position to the noise source.
