Abridged Optics — Transmissibility Calculator v1.0Based on the single-degree-of-freedom (SDOF) viscous damping model. Real isolators may exhibit multi-DOF behavior, frequency-dependent damping, and nonlinear stiffness. Results are most accurate for well-characterized pneumatic and mechanical isolators in the 1–100 Hz range.
