Sokolov’s principal works deal with acoustics, in particular, the physics of ultrasound and its applications. In 1927 he established the ability of ultrasound to pass through metal without noticeable absorption; he made use of this phenomenon in 1928 to detect flaws in metals. He also developed designs for ultrasonic flaw detectors.
