Transmissibility, in the context of structural dynamics, can be defined as the ratio of the maximum force ( $f_{max}$ ) on the floor as a result of the vibration of a machine to the maximum machine force ( $P_{0}$ ):

TR={\frac {f_{max}}{P_{0}}}=R_{d}{\sqrt {1+(2\zeta \beta )^{2}}}

Where

\zeta

is equal to the damping ratio and

\beta

is equal to the frequency ratio.

R_{d}

is the ratio of the dynamic to static amplitude.
