What animals use infrasound to communicate

By Olivia Bennett

Animal communication: whales, elephants, hippopotamuses, rhinoceroses, giraffes, okapis, peacocks, and alligators are known to use infrasound to communicate over distances—up to hundreds of miles in the case of whales.

Which animals communicate using ultrasonic and infrasound?

Bats, Insects like beetles, moths, praying mantis, dolphins, dogs, frogs and toads, etc. communicate using ultrasonic hearing. Infrasound, is a low-frequency sound less than 20Hz.

Do whales use infrasound or ultrasound?

Baleen and Fin whales use infrasound. Research published in The Journal of the Acoustical Society of America suggests that the whales use infrasound for long range communication, like many other animals. In the end, infrasound is still a relatively new field of study in animal behavior.

Do elephants use infrasound?

With their trumpet-like calls, elephants may seem like some of the loudest animals on Earth. But we can’t hear most of the sounds they make. The creatures produce low-frequency noises between 1 to 20 Hertz, known as infrasounds, that help them keep in touch over distances as large as 10 kilometers.

Do dogs use infrasound?

Signs a Dog Hears Infrasonic Sound Waves. Dogs have the ability to hear sounds with frequencies ranging from around 40 Hz to 60,000 Hz. This means dogs are less sensitive to low frequency (or bass) noises than people. Dogs are therefore not likely to hear infrasonic sounds, however, they may ‘feel’ them.

Do giraffes have vocal cords?

Giraffes do have a larynx (voice box), but perhaps they couldn’t produce sufficient airflow through their 13-foot long (4 meter) trachea to vibrate their vocal folds and make noises. The researchers suspected the reason no one heard giraffe communication was because the sound frequency was too low for humans to hear.

Can bats hear infrasound?

Several animal species are able to hear frequencies well beyond the human hearing range. Some dolphins and bats, for example, can hear frequencies up to 100,000 Hz. Elephants can hear sounds at 14–16 Hz, while some whales can hear infrasonic sounds as low as 7 Hz.

How do cetaceans sound?

All species of marine mammals are known to make sound. … Toothed whales can produce sounds using their larynx as well as specialized air sacs near their blowhole. The larynx is used to produce whistles, while the air sacs are used to produce high frequency echolocation signals.

Can humans hear infrasound?

The human perception of sound at frequencies below 200 Hz is reviewed. … The hearing becomes gradually less sensitive for decreasing frequency, but despite the general understanding that infrasound is inaudible, humans can perceive infrasound, if the level is sufficiently high.

What is an example of infrasound?

Infrasound is sound which extends below the range of human hearing (from 20 Hz down to 0.001 Hz), and it eminates from many natural and man made sources. For example, some animals, such as whales, elephants and giraffes communicate using infrasound over long distances.

Article first time published on

Can whales detect infrasound?

Summary. Mysticeti (baleen whales) and Odontoceti (toothed whales) today greatly differ in their hearing abilities: Mysticeti are presumed to be sensitive to infrasonic noises [1, 2, 3], whereas Odontoceti are sensitive to ultrasonic sounds [4, 5, 6].

Can rhinoceros hear infrasound?

Rhinos have extremely good ears, picking up “infrasound” far deeper than the range of human hearing.

Can horses hear dog whistles?

Well-Known Member. Great to have a whistle for your dog that no human ear can hear. However my horse most certainly can hear it!

What animals Cannot hear?

Naked mole rats are nearly deaf because their ears can’t amplify sound. Naked mole rats have poor hearing because, unlike other mammals, they have abnormal outer hair cells that can’t amplify sound. The animals could be used to model human deafness and help develop treatments.

What are sounds below 20 Hz called?

At the other end of the spectrum are very low-frequency sounds (below 20 Hz), known as infrasound. Elephants use infrasound for communication, making sounds too low for humans to hear. Because low frequency sounds travel farther than high frequency ones, infrasound is ideal for communicating over long distances.

Can humans hear above 20khz?

Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)

How many Hz can a dog hear?

SpeciesApproximate Range (Hz)human64-23,000dog67-45,000cat45-64,000cow23-35,000

Do dolphins have vocal cords?

Although dolphins do not possess vocal cords, they still “speak” using sounds such as whistles, squeaks, and trills.

Does a zebra sound like?

Zebras bray much like donkeys do. However, a zebra’s bray has a wider range of sound. It starts in a very low pitch (like a large cat growling) and ends very high (almost like a squealing pig).

Do snakes have vocal cords?

Snakes have a larynx. However, the larynx is small, and it does not have vocal cords.

How do I block infrasound?

Infrasound can only be blocked by a solid earplug, either custom fitted to the ear canal or sealed with jelly to generate an air-tight seal.

Can babies hear infrasound?

We cannot hear infrasonic waves, as these frequencies are under that, which the human ear can pick up. Despite this, these sounds can pose a great risk to our hearing and our health. The human ear can pick up sounds from 16-20,000 Hz. Lower sounds, in other words frequencies of 2-16 Hz, are called infrasonic.

Can speakers produce infrasound?

Subwoofers are speakers designed to reproduce these frequencies, adding realism to movies, video games and other media. By connecting a variable-frequency sine-wave oscillator to a self-amplified subwoofer, you can produce infrasound.

Do humpback whales have sonar?

Toothed whales and dolphins (for example killer whales and bottle-nose dolphins) use echolocation for hunting and navigating, while baleen whales (for example humpbacks and blue whales) generally produce a series of sounds which are frequently termed ‘songs’ that are used for communicating.

What does a dolphin's melon do?

That giant forehead on the dolphin is called a melon. And it acts like an acoustic lens, aiding in sound recognition. In addition to the melon, the dolphin’s teeth are arranged in a way that they function like antenna, receiving incoming sound. … So dolphins use echolocation to fill in what they can’t see visually.

How do whales use sound waves?

The three main types of sounds made by whales are clicks, whistles, and pulsed calls. Clicks are believed to be for navigation and identifying physical surroundings. … Whales also use their tails and fins to make loud slapping noises on the surface of the water to communicate nonverbally.

What horror movies use infrasound?

Many horror films are known to have used infrasound with both the 2007 film Paranormal Activity and 2002 French psychological-horror film Irréversible heavily utilizing infrasonic sound to create chilling sound effects.

What animals hear ultrasonic sounds?

Ultrasonic sound waves are the waves having frequency above 20,000 hertz. Animals such as bats, dos and dolphins can hear these high pitched sounds. So, the correct answer to this question is dogs, bats and dolphins.

What animals use ultrasound?

Animals such as bats and dolphins send out ultrasound waves and use their echoes, or reflected waves, to identify the locations of objects they cannot see. This is called echolocation.

How do porpoises hear?

Porpoise populations are declining rapidly worldwide. … Like all toothed whales, the Yangtze finless porpoise do not have external ears. It hears when sound reverberates through its head, throat, jaw, and acoustic fat within the mandible.

Can sound waves make you sick?

Increasing exposure to ultrasound in the air causes nausea, dizziness, migraine, fatigue and tinnitus.
