Different biological tissues have different sound speeds, and this affects the time taken for sound waves to arrive at the detector.
On the other hand, we estimate the zero sound speed which leads to the correct explanation of the experimental result connected with the BEC of a gas consisting of spin-polarized hydrogen.
The faster the sound speed, the higher the frequency.
Sound speed is defined as the propagation speed of disturbance in static fluid.
