Sounds which have frequency greater than 20,000Hz are inaudible to human ears are called ultrasonics.
Sonobond Ultrasonics was created in 1960.
Ultrasonics is the science of sound. Ultrasonics are usually used to detect items and measure distance. It is often used in the vetrinary and human medical field.

Ultrasonics can be used as part of a process to break down clay and release gold particles stuck in the material. The high-frequency vibrations caused by ultrasonics can help dislodge the gold particles from the clay, making it easier to extract the gold. However, ultrasonics alone may not be sufficient, and other techniques may also be needed for effective gold recovery.

Three applications for Ultrasonics in the NDT field are checking for the thinning of metals, checking for cracks and fractures on the backside of a metal surface as well as looking for defects in honeycomb structures.
