Sound waves, though deeper into it, not much though, LOL., i do belive it is hectrepascals.

Negative voltage in vibration measurement is used to represent the polarity or direction of the vibration signal. It helps in indicating whether the vibration is in the positive or negative direction relative to a reference point. This information can be important for analyzing the nature and characteristics of the vibration signal.
They use inertia switches.

mainly two types of Vibration measurement: shaft vibration Bearing Vibration
An indirect related measurement of molecular vibration is made with an infrared (IR) spectrometer. IR spectroscopy measures the absorption of infrared light by molecules, providing information about their vibrational modes. This technique is widely used in chemistry to analyze the structure and composition of compounds.
WEIGHT
Addition AND measurement.
Compressional vibration is a term used to describe a vibration that occurs as the result of compression. Compression can be described as when particles are pressed or forced together. Vibration occurs as a result of this pressure.
Kelvin
Vibration
It's a sense organ, used to detect movement and vibration in the surrounding water.
