Abstract In the paper a general procedure is presented for the analytical synthesis of an optimal vibration isolation system of a human body including its sensitivity to vibration. The optimal active suspension of a seat has been obtained analytically for a human body represented alternatively by apparent mass weighted by standard frequency domain curves W(s) depicting discomfort levels. The analytical functions describing the optimal vibration isolation systems (OVISs) have been obtained in the general form for random stationary acceleration excitations, general forms of apparent mass M(s) of the sitting human body and a selected criterion of isolation. Analytical forms of complex functions depicting OVIS are presented for two cases of acceleration excitation: white noise (WN) and narrow band noise (NBN). The influence of particular forms of excitation and weighting function W(s) on the resultant vibration isolation is discussed. The analytical results, illustrated by a numerical example presented in the graphical form have been included.
