Acoustic impedance and sound velocity for different materials - Data from Alan Selfridgae.
The propagation velocity is the velocity of the wave thru a medium. The propagation velocity is dependent upon the medium's characteristics (i.e. density, temperature). The propagation velocity of average human tissue is 1540 m/sec .
Physics and Technical Facts for the Beginner. Arthur Au, MD; Michael Zwank, MD, FACEP. This chapter serves as a basic overview of ultrasound physics and image acquisition. This includes standard machine functionality and transducer manipulation.

Ultrasound is an acoustic wave with frequencies greater than the maximum frequency audible to humans, which is 20 kHz. Diagnostic imaging is generally performed using ultrasound in the frequency range from 2 to 15 MHz. The choice of frequency is dictated by a trade-off between spatial resolution and penetration depth,
