Infrasound has a frequency below normal hearing. Ultrasound waves have a frequency above the normal range of human hearing.
Acoustics is the study of sound, ultrasound and infrasound, that is, waves in gases, liquids, and solids.
Sound too low in frequency to hear (~<20Hz) is called infrasound. Sound too high infrequency to hear (~>20kHz) is called ultrasound.
No, infrasound is the frequency of sound that is too low for humans to hear, below 20 hertz, but is used for communicating by elephants and other animals. Echolocation is normally ultrasound, the frequency above our hearing range, higher than 20,000 hertz, and is used by bats and dolphins in echolocation.
Humans are able to hear infrasound, depending upon frequency and amplitude.
Infrasound has a longer wavelength.
"Sound" is a mechanical wave traveling through a medium. Ultrasound is sound, but its frequency is higher than humans can hear.
Ultrasound is above 18 kilohertz. Infrasound is below 20 hertz.
Infrasound has a frequency below normal hearing. Ultrasound waves have a frequency above the normal range of human hearing.
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.
No, but you can use ultrasound to clean glassware.
The opposite of ultrasound (above the human hearing range) is infrasound (below the human hearing range).
Acoustics is the study of sound, ultrasound and infrasound, that is, waves in gases, liquids, and solids.
Infrasound ( below the range of human hearing ) Sonic Range ( within the range ofhuman hearing ) Ultrasound ( above range of human hearing )
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.
I beg your pardon? Sound is not a person, let alone a living being. >:-(
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.
