Work in this field made it possible to strip off and separate the unwanted noise from the desired seismic signal.
An oil company might use stereo 3-D for interpreting and displaying seismic signals as they bounce through the earth.
Two sub categories exist that are relevant to the source of the seismic signal.
A complete instrument package that records seismic signals is called a seismograph.
It is often difficult to generate an ideal seismic signal in a downhole location.
The charge sizes were chosen so that if the decoupling worked as predicted, the seismic signals would be similar in intensity.
Kurtosis has also been used to distinguish the seismic signal generated by a person's footsteps from other signals.
These seismic signals usually have the period of 6 2 seconds.
When detecting seismic signals, the animals lean forward and put more weight on their larger front feet; this is known as the "freezing behaviour".
An individual running or mock charging can create seismic signals that can be heard at great distances.
