; } function PdfDocPage({ name, accent }) { return Chapter 2: Sound Sound is a mechanical, longitudinal wave. It carries energy through a medium by compressing and expanding the particles in its path, which means it cannot travel through a vacuum. Frequency is the number of cycles per second, measured in hertz. Sonographers control some acoustic parameters, while others are determined only by the medium.

Remember: propagation speed in soft tissue is 1540 m/s. It depends on the medium, never on the sonographer.

Period and frequency are reciprocals. As frequency goes up, period goes down. If you know one, you can always find the other.
