ground noise

[′grau̇nd ‚nȯiz]
(engineering acoustics)
The residual system noise in the absence of the signal in recording and reproducing; usually caused by inhomogeneity in the recording and reproducing media, but may also include tube noise and noise generated in resistive elements in the amplifier system.
(geophysics)
In seismic exploration, disturbance of the ground due to some cause other than the shot.
