I propose a new experimental method to measure acoustic properties of liquid and soft material. The resonance method utilizes eigenvibration modes to determine elastic properties of a sample with given density, size, and shape [1, 2, 3]; it has been used for many solid samples, even at high temperatures up to ∼1800 K [4]. A new of idea vibrating a liquid sample together with its solid container enables us to apply the resonance method even to liquid, or extremely soft material. For that experimental analysis, I have developed the xyzr algorithm which enables us to calculate eigenfrequency of bored and laminated objects. I have conducted preliminary experiments on soft plastic (Juracon) accommodated in an aluminum tube and silicone rubber in a copper tube. I succeeded in identifying several peaks on that composite systems, and recalculated v_s=950 m/s for Juracon and V_s=220 m/s for silicone rubber, respectively. The resonance method enables us even to determine Q-value from peak width. Those Q is 59 for Juracon and 580 for silicone rubber, respectively at around 70 kHz.
