In this paper, the method of measuring the impedance within the impact time to have used the impulse hammer for the source was examined. The vibration velocity of the slab in the impact time was considered when driving point was near a restraint the slab. It is shown that the feature is due to the reflected wave from a restraint the slab of driving point. Moreover, a frequency characteristic the lower right when the influence of the reflected wave had been received was shown. It was shown that the presence of the object by which the reflected wave was given from the vibration velocity of the slab in the impact time was appreciable from the above-mentioned finding.
