Sensor array noise reduction is provided. In one possible implementation a logging and control system includes a sensor array noise reduction manager configured to receive measurements from two or more sensors and apply a selected demixing vector to filter one or more noise sources from the measurements and improve a signal to noise ratio of a telemetry signal in the measurements. In another possible implementation a sensor array noise reduction manager for improving a signal to noise ratio of a signal includes a sensor interface configured to receive the signal, which includes information associated with an operating condition, from two or more sensors. The sensor array noise reduction manager also includes a noise reduction module to simultaneously remove noise associated with one or more noise sources from the received signal through use of a demixing vector.
