At what waves can humans NOT hear?
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.
What do you understand by following terms-infrasonic waves?
Sound waves at frequencies lower than humans can hear.
What are ultrasonic and infrasonic waves?
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)

What is the difference between infrasonic audible and ultrasonic 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.
What do you mean by infrasonic waves?
Infrasonic waves are low-frequency sound waves that have a frequency below the human hearing range, typically below 20 Hz. These waves can be generated by various natural phenomena like earthquakes and weather patterns, as well as by man-made sources such as machinery and explosions. Despite being inaudible to humans, infrasonic waves can still have effects on our surroundings and physical environment.
Why do animals often behave strangely before an eruption?
Before an eruption, the Earth's surface starts vibrating. This vibration causes infrasonic sound waves which are below the audible range of human hear (i.e. 20Hz-20kHz). But some animals can hear these infrasonic waves and are aware of the danger. So they start moving in a direction opposite to the source of these waves. Birds take to the air.
What frequencies of sound are infrasonic?
Any frequency that is lower than those that humans can hear - that is, lower than about 20 Hz.
What is the difference between ultra sonic and infrasonic sound?
sound waves with frequencies 20 hertz or lower are infrasonic and waves above 20,000hertz are ultra sonic!
What are the uses of infrasonic waves?
So that you can have fun in the water.

Which animals can hear infrasonic sound?
Animals that can hear infrasonic sounds are; frogs snakes ants dogs fishes whales beetles pigeons Usally, small animals can hear infrasonic sounds because they catches low frequency sound which is less than 20 Hz, especially insects. You may have observed that even if you walk very softly on the floor, animals like dogs feels your coming because they can hear infrasonic sounds.
