Ultrataajuuksista

Ultrataajuuksista, sometimes referred to as ultrasound, are sound waves with frequencies higher than the upper audible limit of human hearing. This limit is typically considered to be around 20 kilohertz (20,000 Hz). Ultrasonic waves are used in a wide range of applications due to their ability to penetrate materials and generate detailed images.

One of the most well-known uses of ultrasound is in medical imaging, known as ultrasonography. This non-invasive technique uses high-frequency sound waves to create images of internal body structures, such as organs, tissues, and fetuses during pregnancy. The sound waves are transmitted into the body and then reflected back as echoes, which are processed by a computer to form an image.

Beyond medical diagnostics, ultrasound technology finds application in industrial settings for non-destructive testing, cleaning, and welding. In sonar systems, ultrasound is used for navigation, depth measurement, and detecting underwater objects. It is also employed in veterinary medicine for similar diagnostic purposes as in human medicine. The precise frequencies and intensities used vary greatly depending on the specific application.
