What is the speed of sound in soft tissue?

Explanation:
In ultrasound, the speed of sound in soft tissue is governed by how stiff the tissue is and how dense it is. Soft tissues have a balance of elasticity and density that makes sound travel about 1.54 kilometers per second. Practically, that means sound moves roughly 1.54 millimeters in one microsecond, which is why depth in ultrasound is calculated from time using the approximate speed c ≈ 1.54 × 10^3 m/s. This value sits between the very slow speed in air (about 343 m/s) and speeds found in much denser solids, so soft tissue commonly uses 1540 m/s as the representative speed.
