Sound Velocities
283
Appendix B: Sound Velocities
Table 41 on page 283 consists of 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, establish the sound velocity in a given material by first testing a sample of
the material.
