Abstract
THE absorption of ultrasonic waves in liquids has been the subject of many investigations. In particular, many measurements have been made of the absorption in water as a function of the temperature and frequency. For frequencies of 5 mc./s. and more, the latest published results for water agree well and seem to be accurate1. If a is the absorption coefficient and f the frequency, a/f2 is found to be independent of the frequency and is 21 × 10-15 m.-1/sec.2 at 25° C. For frequencies near 1 mc./s. the absorption coefficient is approximately 0-2 db./m. This is too small to be measured accurately by the known methods.
