Sound Velocities 217
Appendix B: Sound Velocities
The following table lists the sound velocities in a variety of common materials. Use
this table only as a guide. The actual velocity in these materials may vary significantly
due to a variety of causes, such as composition, preferred crystallographic orientation,
porosity, and temperature. Therefore, for maximum accuracy when establishing the
sound velocity in a given material, first test a sample of the material.
