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.
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.
No. Sound ABOVE 20,000 hz is ultrasound.
