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
Beyond medical diagnostics, ultrasound technology finds application in industrial settings for non-destructive testing, cleaning, and welding.
