As shown in a parametric study, passive isolation systems , do not address all the requirements/concerns of an ideal isolation scheme, simultaneously; their effectiveness in addressing one isolation requirement is normally realized at the expense of either not being effective in or adversely affecting other requirements. This is also true for the more elaborate ‘two stage mounting’ (known as ‘double mounting’) scheme.

As an alternative to passive isolation solutions, the parameters of which are fixed and can not be changed once such solutions are put in place, one can use adjustable-passive (also known as semi-active) isolation schemes, such as DEICON’s Computer Controlled Air Isolation System. Such systems allow for the in-situ adjustment of the mounting parameters modifying the isolation system such that it best suits the instantaneous isolation requirement on hand.
