Experimental studies of the influence of human standing positions on the feet-to-head transmission of vibrations

The experiments performed on a especially built test stand, concerning the influence of human body position on the feet-to-head vibration transmission are presented. The investigations have been performed for chosen amplitudes and frequencies of source acceleration excitations coming from a vertical shaker. The big influence of standing positions of a human body on the transmitted accelerations from feet to head has been measured and analyzed. Numerical results of variability of experimental studies have been statistically elaborated and graphically presented.
