The human ear cannot detect all possible frequencies. It has evolved to detect frequencies of sounds that are the most useful to humans, and has a maximum frequency range of about 20Hz to 20kHz, which decreases as you get older, particularly at the higher end.
Infrasonic describes sounds that are too low in frequency to be heard by the human ear, and ultrasonic describes sounds that are too high in frequency to be heard by the human ear. These sounds cannot be heard by the human ear because they are outside of its range of capability.
Humans cannot hear ultrasonic (above 20,000 Hz) and infrasonic (below 20 Hz) waves. Ultrasonic waves are too high in frequency for the human ear to detect, while infrasonic waves are too low.
Frequencies above 20,000 Hz (ultrasonic) and below 20 Hz (infrasonic) are generally not audible to humans. Ultrasonic frequencies are commonly used in technology applications such as medical imaging and pest control, while infrasonic frequencies are often associated with natural phenomena like earthquakes and ocean waves.
Infrasonic waves have frequencies below the range of human hearing (less than 20 Hz), audible waves fall within the range of human hearing (20 Hz to 20,000 Hz), and ultrasonic waves have frequencies higher than what humans can hear (greater than 20,000 Hz). Each type of wave has different applications and effects on living organisms.
Ultrasonic noise can be harmful to humans and the environment. Excessive exposure to ultrasonic noise can cause hearing damage and other health issues in humans. In the environment, ultrasonic noise can disrupt wildlife and ecosystems, affecting their behavior and communication.
Ultrasonic noise can be harmful to humans and the environment. Excessive exposure to ultrasonic noise can cause hearing damage and stress in humans, and can also disrupt wildlife and marine life. It is important to limit exposure to ultrasonic noise to protect both human health and the environment.

Infrasonic waves are waves which are below humans hearing range while ultrasonic waves are waves which human beings can hear. Example-bat,dog etc and human beings (respectively)

Ultrasonic sound can potentially harm humans at high levels, causing discomfort, hearing damage, and other health issues.
I have witnessed no levitation, ever.
Ultrasonic sound is generally not harmful to humans at normal levels. However, exposure to very high levels of ultrasonic sound can potentially cause discomfort or hearing damage. It is important to use caution and limit exposure to very high levels of ultrasonic sound.
Sound waves at frequencies lower than humans can hear.
