Abstract
A method for dual telemetry noise reduction on a drilling rig comprises receiving an acoustic signal including first telemetry data transmitted over a drill string of the drilling rig. A pressure signal is received including the first telemetry data transmitted through drilling mud of the drill string of the drilling rig. The pressure signal is substantially similar to the acoustic signal and offset from the acoustic signal by a first period of time. The telemetry data is determined and the noise contained within the acoustic signal and the pressure signal rejected responsive to both the received acoustic signal and the received pressure signal.
