Many animals such as porpoises and bats use their ultrasound ability for locating obstacles and prey. Moreover, these are also used for cleaning, mixing and accelerating the chemical processes as well. These can be even used to detect and examining invisible flaws as well. The functions of ultrasound are not limited to the testing pregnancy only.
Overall these machines are used to detect objects and measure their distances also. The speed of ultrasound waves varies from person to person and normally 20 kHz in young and healthy adults. It is not different from the normal sound except in the case of the human that cannot hear it. The waves generated by the ultrasound machines contain highest frequencies as compared to the upper audible limit of human hearing. Most of the time ultrasound scanning is used to examine the fetus of a pregnant woman. Ultrasound refers to those vibrations and sounds that have an ultrasonic frequency and is used during the medical imaging process.
