Acoustic impedance and sound velocity for different materials - Data from Alan Selfridgae.
The document lists various materials and their corresponding sound velocities when tested with ultrasound. It provides the velocity of sound in inches per microsecond and metres per second for over 30 common materials including metals, plastics, liquids and other substances.
For most humans audible sound ranges between 20 Hz and 20,000 Hz (20 kHz) Ultrasound refers to any sound waves with frequencies greater than 20kHz. Diagnostic ultrasound typically uses frequencies between 2 and 20 million Hertz (Megahertz - MHz)
15 gru 2021 · Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more.
