Abstract
A measuring method for vibration sensation is significant only when it leads to the measuring the influences on human organism.
This experiment tried to clarify how grade of vibration influence on the organic function, specifically on heart-rate, frequency of respiration, and secretive quantity of saliva and the evaluation by introspection method and the rate of vibration amplitude were taken into account.
We have come to the conclusion that a vibration whose amplitude is between 0.5 and 7mm and whose frequency is about 2Hz has a pleasant vibratory influence on human organism and whose frequency is below 1Hz or above 4Hz has an excessive influence and therefore unpleasant, vibratory influence.
