Difference is in their frequency, audible sound waves is between 12 Hz and 20,000 Hz, Ultrasound waves is any sound that has a frequency beyond the 20,000 Hz limit
Infrasound has a frequency below normal hearing. Ultrasound waves have a frequency above the normal range of human hearing.
Ultrasound.

Infrasound is always smaller or lighter than ultrasound. For example: infrasound can be the sound of a paper clip hitting the floor, and ultrasound can be the sound of two planets colliding.
Ultrasound technology uses sound waves bouncing off tissues to look inside the body. Ultrasounds are used for imaging. Shockwave therapy uses sound to obliterate small objects; it is used to treat kidney stones.
Sound waves are resulted due to vibrations.
Endorectal ultrasound (ERUS) is a procedure where a probe is inserted into the rectum and high frequency sound waves (ultrasound waves) are generated
u figure it out dude
Ultrasound sound waves
Ultrasound is the name of the proceedure; a Sonogram is the picture image produced by an ultrasound scan.Therapeutic ultrasoud uses low frequency sound waves to penetrate deep into the injured tissue during rehabilitation. This form of ultrasound creates heat using the lower frequencies, and the heat will help heal the injury. These sound waves are sent into the body using a transducer with no intent or way to capture any return they may have. Thus, no image is created. The sound waves are instead used and converted into heat energy.Medical ultrasound used for imaging purposes, including pregnancy, uses higher frequency sound waves. The transducer (the small wand-like structure used during the exam on the skin surface) creates these sound waves, sends them into the body, and when they bounce off of structures and return to the transducer they are captured and converted to mechanical energy and displayed on the monitor.
The sound waves which are below the audible sound are called infrasonics(<20Hz) and The sound waves which are above the audible sound are called ultrasonics(>20KHz).
Ultrasound is non-invasive and therefore lower risk. It is the use of high-frequency sound waves to visualize the interior of the body, typically to "see" the fetus. Amniocentesis is the extraction of amniotic fluid from the uterus via a big needle.
