Vibration measurement

Definition

Vibration measurement refers to the process of quantifying the amount of vibration experienced by an object or system, often using specialized sensors and equipment to capture and analyze vibration data. This process is crucial for understanding how vibrations can affect structural integrity, comfort levels, and noise generation in high-frequency noise scenarios. Accurate vibration measurements can inform design improvements and maintenance practices to mitigate unwanted effects.
