Transmissibility (vibration)

Transmissibility is the ratio of output to input.

Transmissibility (T) = output/input

T>1 means amplification and maximum amplification occurs when forcing frequency (f_f) and natural frequency (f_n) of the system coincide.

There is no unit designation for transmissibility, although it may sometimes be referred to as the Q factor.

The transmissibility is used in calculation of passive heave compensation efficiency.
