Abstract: A system is described for calibrating fiber optic well measurements including a fiber optic waveguide disposed proximal to a wellbore, a sensor coupled to the fiber optic waveguide, the sensor configured to record a plurality of signals detected by the waveguide, and a computer system configured to calibrate the signals from the waveguide by filtering out one or more background acoustic responses from the plurality of signals. A method for calibrating the signals is also described.
