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.
What else can I help you with?
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 do you understand by following terms-infrasonic waves?
Sound waves at frequencies lower than humans can hear.
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 are some disadvantages of infrasonic sound?
Some disadvantages of infrasonic sound include limited range of propagation due to absorption by air, potential interference with sensitive equipment or structures, and the possibility of causing discomfort or health issues in humans and animals at high intensity levels.
Which animal can hear infrasonic?
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.
Can humans hear infrasonic waves?
With special technology, yes
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!
How many hertz are needed for a sound to be infrasonic?
Sound below about 20 Hertz (20 cycles per second) is considered infrasonic. A link can be found below.
What is a sound receiver?
where people or animals hear from
Do all animals hear the same frequencies of sound as humans do?
No, animals do not hear the same frequencies of sound as humans. Different animals have different ranges of hearing, with some able to hear higher or lower frequencies than humans.
Can animals hear the same sounds?
The sounds animals can hear is based on the frequency that the certain animal can hear. For example, dog's can hear at much higher frequencies then humans can, so if a sound is made that is above our capability of hearing, we will not hear the sound, but the dog will.
What name is given to the sounds which a cat can hear but a human cannot?
Sound with a frequency lower than about 20 cycles per second, called infrasonic sound. Sound with a frequency higher than about 20,000 cycles per second, called ultrasonic sound. Only those with excellent hearing can perceive sound at these extremes. As we age and as our hearing is damaged by exposure to loud sounds, the frequency range of hearing is reduced. Some animals can hear sounds above and below the range of humans.
