What is the propagation speed of bone?

Explanation:
Sound travels through bone much faster than through soft tissues because bone is stiffer and denser. For cortical bone, longitudinal waves propagate around 3,500–4,000 m/s, with measured values near 4,000 m/s. The figure 4,080 m/s fits this range, making it the best match. The other speeds (roughly 1,460–1,600 m/s) are typical of soft tissues, not bone, which is why they’re not correct for bone propagation.
