Sonic infrasound is a sound too low for humans to hear, below 20 Hertz. Ultrasound is a sound too high for humans to hear, above 20,000 Hertz.
Infrasound refers to sound waves with frequencies below the range of human hearing (below 20 Hz), while ultrasound refers to sound waves with frequencies above the range of human hearing (above 20 kHz). Infrasound is used in monitoring seismic activity and animal communication, while ultrasound is used in medical imaging, industrial cleaning, and pest control.
Ultrasound is above 18 kilohertz. Infrasound is below 20 hertz.
"Sound" is a mechanical wave traveling through a medium. Ultrasound is sound, but its frequency is higher than humans can hear.
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.
Infrasound is sound that is lower in frequency than 20 Hz (Hertz) or cycles per second, the normal limit of human hearing. Ultrasonic waves have frequencies above the audible range at around 20 kHz. Audible sound is within human hearing range.
Infrasound.
Sound below 20Hz is considered infrasound, while ultrasound typically refers to sound frequencies above the human hearing range (above 20kHz).
The same way you record normal sound. infra sound is the same as normal sound but our ears cannot hear it. a microphone would.
I beg your pardon? Sound is not a person, let alone a living being. >:-(
Infrasound waves are sound waves with frequencies below the audible range for humans, typically below 20 Hz. Ultrasound waves are sound waves with frequencies higher than the audible range, typically above 20,000 Hz. Both types of waves are used in various applications, such as infrasound for communication among elephants and ultrasound for medical imaging.
Humans can't hear sounds that are below 20Hz (infrasound) or above 20,000Hz (ultrasound). Infrasound is produced by natural phenomena like earthquakes and by some animals, while ultrasound is used in medical imaging and by animals like bats for echolocation.
Sounds can be classified into three main categories based on their frequency: infrasound (below 20 Hz), audible sound (20 Hz - 20 kHz), and ultrasound (above 20 kHz). Infrasound is felt more than heard, while ultrasound is not audible to the human ear but can be detected by some animals.
