In wood the speed of sound varies with grain direction because the transverse modulus of elasticity is as little as 1/20 the longitudinal value. The speed of sound across the grain is about one-fifth to one-third of the longitudinal value. There is no recognized independent effect of species of wood on the speed of sound. Variability in the speed of sound relates to the variability of modulus of elasticity and density.
