Evaluate SDOF vibration isolation response
Calculate displacement transmissibility for a single-degree-of-freedom system from natural frequency, forcing frequency, damping ratio and base amplitude.
Frequency ratio • damping • transmissibility

How this Vibration Transmissibility Calculator works
For base excitation, displacement transmissibility equals the square root of 1 plus the damping term divided by the dynamic denominator. Frequency ratio is forcing frequency divided by natural frequency.
Important: Real machines can have multiple modes, nonlinear mounts and structural resonances. Confirm the model and units with vibration measurements.
What assumptions should I verify?
Verify every entered quantity, rate, unit, product specification and local requirement before relying on the estimate. U.S. conventions are primary where location matters.
Is information sent anywhere?
No. Calculations run locally in the browser and this calculator sends no entered information to a remote service.
