Measuring Vibration with Accelerometers

Jul 15, 2021Vibration is most commonly measured using a ceramic piezoelectric sensor or accelerometer. An accelerometer is a sensor that measures the dynamic acceleration of a physical device as a voltage. Accelerometers are full-contact transducers typically mounted directly on high-frequency elements, such as rolling-element bearings, gearboxes, or spinning blades.

Physics Tutorial Natural Frequency

All objects have a natural frequency or set of frequencies at which they naturally vibrate. The quality or timbre of the sound produced by a vibrating object is dependent upon the natural frequencies of the sound waves produced by the objects. Some objects tend to vibrate at a single frequency and produce a pure tone. Other objects vibrate and produce more complex waves

The damper's purpose is to prevent vibration of the strings by pushing down on them. When you play a key, the damper is lifted off and the related string is then free to vibrate. As long as you hold the key down, the string will continue to vibrate, but when you release the key, the damper falls back on the string stopping its vibration.
