★ Infrasonic

$\longrightarrow$ Infrasound refers to the sound with frequency lower than 20 Hz which cant be heard by humans.

$\longrightarrow$ Infrasound is used to stabilize myopia in young kids.

$\longrightarrow$ Infrasound is influenced by the atmosphere so it can be used to monitor the activities of the atmosphere.

$\longrightarrow$ In particular, natural disasters such as volcanic eruptions, earthquakes etc can be forecasted by monitoring the infrasonic waves.

★ Ultrasonic

$\longrightarrow$ Ultrasound refers to the sound with frequency higher than the upper limit (20 kHz) of frequencies audible to normal human ears.

$\longrightarrow$ Ultrasound is commonly used to find flaws in materials to measure the thickness of objects, to find physical abnormalities in various parts of human body, as well as in the form of a sound ranging device called SONAR.

$\longrightarrow$ Ultrasound is not influenced by any such factors

$\longrightarrow$ in particular, ultrasound is also used in micro welding. The weld is produced by the application of high frequency vibratory energy as the parts are held together with force.
