Following is a chart of common vibration scenarios with the appropriate frequency weighting factor for each axis. We live in a world of frequencies and i have come to the conclusion that our body is part of this world and has its frequencies too.
Human Vibration Hand Arm Vibration Whole Body Vibration
Human body vibration measurement. Measurement of vibration transmitted to the human body by the seat surface the backrest or the feet to iso 2631 for application with a triaxial seat pad accelerometer eg. They are basically a set of filters that must be applied to the acceleration data in order to make evaluations and assessments on the effects of vibration on human beings. What is the human vibration frequency exactly. The dats software provides a human biodynamics package that includes a whole body vibration assessment report. The vibration weighting values are defined in iso80412005. Introducing the hvm200 human vibration meter.
Model ks963b100 s measuring duration from 1 minute to 1 day. Measurement of the human biofield and other energetic instruments by ms. It thus givestime exposure levels or doses in percent of permitted vibration exposure for up to 24 hours. The hvm200 is a small rugged vibration meter with built in wi fi that can be used to measure hand arm whole body and general vibration. The main purpose of measuring human vibration is the prevention of health risks and the evaluation of comfort for example in vehicles. Let us suppose that the acceleration of a vibrating plat form is measured and that the instantaneous acceleration values measured are plotted on the time axis for a total measurement.
The standards for measurement of human vibration for instance iso 2631 1978 take the relationship between versus level into consideration. The iso standards for human vibration measurement require that acceleration be the parameter used to measure vibration levels. Some like to call this the aura light body soul or essence. It thus gives exposure levels or doses in percent of permitted vibration exposure for up to 24 hours. Two categories are distinguished. The standards for measurement of human vibration for instance iso 2631 1978 take the relationship between time versus level into consideration.
It includes the metrics and frequency weightings needed to measure human vibration. If we have a physical body which scientist confirmed a very long time ago we also have a mental body thoughts emotional body e motion energy in motion and therefore we also have a energy body. Hand arm vibrations which are induced via the hands into the body. Measurements with hvm200 human vibration meter when measuring human vibration it is important to use the correct weightings for your measurement situation to account for the different resonances within the human body. I recommend reading a very interesting summary on this topic.
