Ultrasound Case Study:
Ultrasound is the sound pressure wave which can not be heard be a human being. Although, the sound wave is so high that a human can not hear it, the existence of ultrasound has been always obvious to people. Not long ago people learnt to use the abilities of ultrasound for their needs, for example, in health care, veterinary and industry. Ultrasound has the limit of 20000 hertz, and when the power of the wave is increased, the sound can be used for destructive purposes. It is obvious that human ear is not sensitive enough to catch ultrasound, but there are animals, birds and insects which exist only due to the well-developed sound perception and use ultrasound to find out about their location in the space (for example, bats, whales, dolphins, the latter even produce ultrasound for communication with one another). Animals generally hear ultrasound, because it is important for their life and people use this ability to train dogs using the ultrasound whistles.
Ultrasound is used in human medicine and opens wide opportunities for scientists. With the help of the ultrasound and ultrasonography a doctor can see the human organs, their shape and their condition on the computer screen. Today nearly every pregnant woman is diagnosed with the help of medical sonography to see the condition of the fetus and probably get to know about its gender.
Then, ultrasound is used in health care, physics, chemistry and for the domestic and military purposes.
