What is another word for cymograph?
Pronunciation: [sˈa͡ɪməɡɹˌaf] (IPA) 
A cymograph is a scientific instrument used for measuring vibrational waves, particularly in sound. Other terms synonymous to this instrument include oscillograph, seismometer, seismoscope, sonograph, and vibrometer. An oscillograph is specifically used for recording electric oscillations, while a seismometer and seismoscope are devices primarily used to detect and measure earthquakes; the former measuring the overall motion of an earthquake while the latter only indicates the shaking that comes from the ground. Sonograph, on the other hand, primarily refers to devices that create images from sound, while vibrometer is used to measure vibration in machinery and structures. Despite their differing applications, all these devices share a common function - measuring motion and vibrations.
