# Speed of sound in a solid calculated theoretically

I am trying to find theoretically precise values of the speed of sound in various solid materials. I have found the CRC Handbook of Chemistry and Physics with a table of values with no uncertainties reported, I don't know if I should interpret this as if these values are theoretical, or as if they just did not bother to state the uncertainties. https://hbcp.chemnetbase.com/faces/contents/InteractiveTable.xhtml

I also know that it would in theory be possible to compute the longitudinal speed of sound by using $$\sqrt{\frac{K+\frac{4}{3}G}{\rho}}$$ with K,G,$$\rho$$ being bulk modulus, shear modulus, and density. Is this how they calculated it? if not, is there any database where I can find the information I'm looking for?

$$c = \sqrt{\frac{E}{\rho}}\,$$
