This paper describes expressions and computational graphs to determine a frequency respons parameters of transmissibilities with antiresonant point. Generally, a vibrational amplitude in the resonance can be reduced the vibration isolation countermeasure by vibration-proof materials and dynamic vibration absorber with damping. This study replaced dynamic vibration absorber with the simplest mass-spring system, a vibrating elements of a primary vibration system are assumed viscoelastic materials which have equivalent models of complex spring constants. When ratios of mass ratio and spring constant ratio of two-degree-of-freedom equivalent system are 1,the analytical results of which the interval of two angular frequencies of right and left of the antiresonant point was obtained the square root of mass ratio. Vibraional transmissibilities with the antiresonant point are measured experimentally.
