Sound Velocities
307
Appendix A: Sound Velocities
Table 25 on page 307 lists the ultrasonic velocity in a variety of common materials.
This is only a guide. The actual velocity in these materials might vary significantly
due to a variety of causes, such as, composition, preferred crystallographic
orientation, porosity, and temperature. For maximum accuracy, establish the sound
velocity in a given material by first testing a sample of the material.
