The variation of ultrasonic velocity and absorption in sperm oil and seal oil with temperature range of 5–55 C and frequency range of 1.5–60 MHz are measured. In both oils, the velocity increases ca. linearly with decreasing temperature and increases with increasing frequency; the absorption increases not only with decreasing temperature but also with decreasing frequency.
