As defined by ISO 8041, a Human Vibration Meter (HVM) is a device that uses a vibrational transducer, signal processor, and display to measure human response to vibrations. HVM is typically used in hand-arm vibration measurements to prevent HAVS. In whole-body, they are typically used for the calculation of Vibration Dose Value.
What is a Human Vibration?
Human vibrations are mechanical vibrations that are transmitted directly to the human body, affecting different tissues in different ways. There are three types of human vibrations:
hand-arm vibration (ISO 5349);
whole-body vibration (ISO 2631);
low-frequency whole-body vibration in the frequency range from 0,1 Hz to 0,5 Hz (ISO 2631)
