Infra-sonic refers to sound frequencies below the lowest human hearing range so are around 15Hz or lower.
Many aquatic animals are able to sense low frequencies as a warning of approaching predators for example. Vibrations set up by fish or other marine dwellers travel for great distances.
On land, many mammals are reported to react to very low frequency sounds such as those preceding earthquakes.
Elephants use low frequency calls that travel for many mile to other elephants, mostly at frequencies below the range of human hearing.
What else can I help you with?
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.
Can humans hear infrasonic waves?
With special technology, yes
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)
Infrasonic wave and ultrasonic wave?
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)
At what frequency is ultrasonic and infrasonic?
Human ears can hear frequencies between about 20 and 20,000 Hz, so anything below 20 is infrasonic, and anything above 20,000 Hz (20 kHz) is ultrasonic.
What frequencies of sound are infrasonic?
Any frequency that is lower than those that humans can hear - that is, lower than about 20 Hz.
Can you hear infrasonic sounds using any devices?
Yes, infrasonic sounds are below the threshold of human hearing, typically below 20 Hz. To detect and record infrasonic sounds, specialized equipment such as infrasound microphones or sensors are used. These devices are designed to pick up low-frequency sounds that are not audible to the human ear.
Why does the cattle's ability to hear infrasonic frequencies contribute to a stampede?
The cattle's ability to hear infrasonic frequencies contributes to a stampede because these sounds are not heard by the cattle drivers and they are not able to react prior to the stampede. The continued sounds cause the cattle to keep running.
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 are the example of infrasonic sound?
Examples of infrasonic sounds include earthquakes, thunder, volcanic eruptions, and some animal calls, such as those of elephants and whales. These sounds have frequencies below the range of human hearing (below 20 Hz).
