A new instrument has been developed for rapid continuous recording of temporal changes in ultrasonic velocity and attenuation constant in a material. A set of data of changes in velocity and attenuation is obtained within the interval of one echo train, usually 0.1 msec or longer. A high-speed minicomputer is used for controlling the whole electronic system and data processing. The accuracy is 10−5to 10−6for the velocity change and 10−3for the attenuation change in a sample length of 3 cm. Data showing the speed and accuracy of the instrument are given.
