Vibrating reed technique makes a thin board vibrate, and the modulus of elasticity of the material can be conducted by measuring that resonance frequency. Using this method, authors showed that the dependence of temperature of the resonance frequency could be different due to the existence of hydrogen absorption. A change in the resonance frequency is equivalent to observing a change in hardness of the material. However, the comparison of hardness of the material adsorbed hydrogen couldn't be discussed because the value of the measured the resonance frequency was different depending on the dimension precision of the samples or the fixed condition. In this paper, samples were made with a laser beam cutter, which improved the dimension precision. Then, the goal was to compare the absolute value of the resonant frequency of the metal, which was absorbed with hydrogen, with that of the metal, which contained no hydrogen.
