cymograph

the cymograph was used to record the vibrations of the earth.

scientists developed a new cymograph to measure sound waves.

the cymograph helps in understanding seismic activity.

using a cymograph, researchers can analyze wave patterns.

the accuracy of the cymograph is crucial for geological studies.

we need to calibrate the cymograph before the experiment.

the cymograph's data revealed unexpected results.

engineers designed a portable cymograph for fieldwork.

the cymograph recorded the frequency of the sound waves.

by analyzing cymograph readings, we can predict earthquakes.
