What is the speed of sound in an ultrasound machine?

  • Speeds of sound in common media and tissues are listed in Table 2-1. For soft tissues, the average speed of sound has been found to be 1540 m/sec. 1 Most diagnostic ultrasound instruments are calibrated with the assumption that the sound beam propagates at this average speed.
