acoustic velocity

For a given type of rock, acoustic velocity varies indirectly with porosity.

However, the sonographic instrument assumes that the acoustic velocity is constant at 1540 m/s.

Therefore any sound field can be reconstructed, if sound pressure and acoustic velocity are restored on all points of the surface of its volume.

The resulting normal shock wave then propagates upstream at an effective acoustic velocity until the flow mismatch reaches equilibrium.

Some common earth properties that are inverted for include acoustic velocity, formation and fluid densities, impedance, poisson's ratio, formation compressibility, shear rigidity, porosity, saturation etc.

Depth conversion is an important step of the seismic reflection method, which converts the acoustic wave travel time to actual depth, based on the acoustic velocity of subsurface medium (sediments, rocks, water).

Although it may not be obvious, this equation shows that acoustic velocity is dependent on the temperature of the air (the medium), which is also dependent on the pressure, which is also dependent on the altitude.
