Top 10 Noisiest Animals on the Planet

Scientists have measured the sounds made by creatures in nature and they surprised themselves. Here, the studies just want to emphasize that animals can potentially create sounds so loud that they can puncture our human eardrums. Join us in taking a look at the noisiest 'knights' in nature according to National Geographic magazine.

1. Blue Whale - Ocean Singer

The blue whale is the loudest animal on record, reaching up to 118 decibels. Blue whales do not sing complex ‘songs’ like humpback whales, but their low-frequency calls – below the human hearing threshold – can be heard from more than 500 miles away. Calculations from the 1970s by scientists Roger Payne and Douglas Webb suggested that the song of the blue whale could travel across the ocean.

The blue whale ‘sings’ louder than a jet plane (140 decibels). The loudest human scream reaches just over 70 decibels. The threshold for sound that causes pain in humans is between 120 and 130 decibels. A few years ago, researchers noticed that the whales were reducing the frequency of their singing.

Blue whales are known as the wandering singers of the oceans. Because the blue whale can emit ultra-low frequency sounds at 14 Hz. And it also emits the loudest sound in the world, louder than the screech of a jet plane at 200 decibels. Compared to a human scream at 70 decibels, sounds higher than 120 decibels are dangerous to human ears.

It is not clear what the purpose of these calls is. Richardson et al. (1995) suggested several possible reasons:

Maintain distance between individuals
Recognize species and individuals within species
Communicate information (feeding, alarm, courtship)
Maintain social organization (e.g. calls between males and females)
Mark the location of food sources)

2. Screaming Monkey - The Loudest Land Creature

Screaming monkeys are the loudest land creature. The largest population of these creatures live in the rainforests of South America. Some say their screams are actually more like roars, and can be heard up to 3 miles away. The volume of a screaming monkey's scream has been measured at 88 decibels from 16 feet away, which is about the same as a subway train running on a track (95 decibels). Screaming monkeys are second only to the blue whale in terms of the volume of sound they produce.

Research has shown that screaming monkeys 'scream' using a U-shaped hyoid bone in the animal's throat. This bone doesn't actually hook onto any other bones, so it just seems to hang there. The enlarged bone forms a throat sac that helps resonate the scream before it breaks out of the animal's mouth.

Monkeys scream for many different purposes, screaming to announce their location, to protect their territory, to protect their friends, but humans still do not know their ‘vocabulary’.

Adult male monkeys always love their baby monkeys even if they are not their own. After birth, each baby monkey usually has a male monkey taking care of it. When it feels danger, the baby monkey runs to the member responsible for taking care of it for protection and comfort. The male does not necessarily have to be the baby monkey’s father, he takes on the role of taking care of the little member like a nanny.

3. Oilbirds - Still Making Noise While Sleeping

When oilbirds return to their burrows to roost, the loudest flocks of birds ever recorded can deafen you. Oilbirds use echolocation to find their way through completely dark caves. However, unlike the calls of bats, oilbirds' squawks are within the human hearing range. Each bird can produce a squawking sound of up to 100 decibels at close range, and a flock of thousands of oilbirds adds up to a terrifying level.

Oilbirds seem to use echolocation only in their burrows, not during their nighttime foraging. This may be because their sensitivity is not as high. A scientific experiment showed that oilbirds would headbutt 10-centimeter-wide plastic discs, but they could avoid 20-centimeter-wide discs and larger ones.

They feed at night on the fruit of tropical palms and berries, and are the world's only nocturnal fruit birds. They forage at night, navigating by echolocation like bats, but with a high-pitched clicking sound in the range of around 2 kHz that humans can hear. Alexander von Humboldt discovered the species while climbing the Teide volcano and arriving in Cumaná, Venezuela on July 16. Von Humboldt visited the Caripe mission and discovered the oilbird.

4. Coqui Frogs - The Loudest Amphibians

Only males of the common coqui frog species sing, and their songs have been recorded at up to 100 decibels (measured from 1 meter away), making them the loudest amphibians ever known. The nocturnal frogs' songs serve two purposes: to announce their territory to other males and to attract females.

In their native habitat in Puerto Rico, coqui frogs are considered part of the island's natural heritage. However, in Hawaii, residents are often kept awake at night by the noise caused by large gatherings of frogs, which is equivalent to running a lawn mower all night, according to the Hawaii Department of Agriculture.

Most are aquatic, with most laying eggs in water and passing through a tadpole stage. There are also a few arboreal species, and a very small number of species can survive in brackish water. Many species are not actually arboreal but live on land and water, many are green, while those that live on land and in water are colored by their environment. They eat insects and other invertebrates. Coqui frogs have molars and clawed toe suckers.

5. Pistol Shrimp - The Loudest Explosion Made by a Living Creature

This tiny Mediterranean shrimp doesn't make a sound with its mouth, or with its body. It uses its giant claws to shoot jets of water with such force that it can create air bubbles. When these bubbles explode, it creates a shock wave that has been measured at over 200 decibels.

More surprisingly, this shock wave can kill other shrimp up to 2 meters away, and can also create a flash of light as hot as the sun. The human threshold of tolerance - the level at which pure sound causes most people to feel pain in their ears - is 120 decibels. The human eardrum will rupture at 160 decibels, which is what the aforementioned giant tiger shrimp can do.

The pistol shrimp doesn’t sing, chirp, scream or whistle, it simply makes the loudest explosion ever made by any living creature. The noise of a pistol shrimp is enough to ‘mask’ submarines from sonar detection.

The pistol shrimp stuns its prey by rapidly closing its special claws to shoot jets of water at 100km/h, creating a low-pressure bubble of air behind it. The bubble bursts, creating a mini-explosion with a sound level of 200 decibels, which stuns and kills its prey.

The pistol shrimp is helping scientists in the UK research a clean and safe source of energy that could give a major boost to the fight against climate change. Thermonuclear power requires a high-speed bullet to create a shock wave and collapse a chamber filled with plasma, and the pistol shrimp is the only creature on Earth that naturally has such power.

6. Mole Cricket Gryllotalpa vinae - Amplifying Singing with Homemade Loudspeakers

The mole cricket Gryllotalpa vinae is the loudest insect. It uses its specialized forelimbs to dig loudspeaker-shaped burrows. Standing inside the burrow, the cricket can chirp loudly enough to be heard from 600 meters away.

A recording device placed 1 meter from the entrance of the cricket’s burrow recorded sounds of up to 92 decibels, louder than a lawnmower. In fact, G. vinae ‘cheats’ by using its burrow to amplify the actual sound emitted from its body, converting 30% of its energy into amplified sound.

A thick-bodied insect, the mole cricket has a head covered with a strong armor that helps protect its head, and has long antennae, about 3–5 cm long, round eyes, and two front legs like two shovels developed for digging and swimming. Moles can also fly - an adult can fly 8 km during the breeding season. They hibernate in winter. Moles are omnivorous, eating larvae, worms, roots, and grass. Predators of mole crickets include birds, mice, skunks, armadillos, raccoons, foxes, chickens, and humans. Moles forage at night and spend most of their time underground in a dense burrow system, so they are rarely seen. They live in fields and grasslands on all continents except Antarctica. In some East Asian countries, people sometimes use mole crickets as food.

7. Micronecta scholtzi Water Bug - Making Noise with Its Penis

Although not the loudest animal in the wild on a purely decibel basis, the Micronecta scholtzi water bug actually makes the loudest sounds relative to its body size, according to a scientific publication in the journal PloS ONE earlier this month.

Experts and evolutionary biologists in Scotland and France recorded the rice-sized water bug singing at an intensity of up to 105 decibels, equivalent to the sound of a sledgehammer hitting the ground at arm's length. Although the sound from the bottom of a pond is greatly reduced when it reaches the surface, the water bug's song is still loud enough for a person standing on the pond's edge to hear.

Notably, the water bug makes noise by rubbing its penis against its abdomen, a process similar to the way crickets 'sing'. Making noise with external genitalia is relatively rare in the animal kingdom, but animals have evolved hundreds of different ways to amplify their ‘singing’.

Micronecta scholtzi is a freshwater beetle or water bug of the family Corixidae that lives in freshwater environments and is common throughout Europe. This insect is about 2cm in size and swims on its back using two long legs that act as paddles, it makes noise by rubbing its penis against its abdomen. Micronecta scholtzi is only 2mm long. This freshwater beetle swims on its back using two long legs that act as paddles.

8. Bulldog Bat

The greater bulldog bat, native to the Caribbean, uses echolocation to find food, like all bats. However, instead of eating the familiar insects, it eats fish. It is capable of emitting sounds that travel through both air and water, reaching up to 140 decibels. These particularly loud sounds are ultrasonic, meaning they are outside the range of human hearing.

The bulldog bat has orange to brown fur, a head length of 7 to 14 cm, and a weight of 20 to 75 g, making it quite large. It has relatively long legs, large feet (especially in the case of the greater bulldog) and strong claws. Its wings are long (up to 60 cm across) and narrow, and its ears are large, funnel-shaped and pointed. Unusually for a bat, it has cheek pouches for storing food. They also have full lips divided by a fold of skin that gives them a 'bunny lip' appearance, along with cheek pouches that give them a pug-like appearance.

Their upper jaw and front teeth are fused to provide strong support for the large upper middle incisors. Dental formula: 2/1, 1/1, 1/2, 3/3 = 28. The molars are tuberculous. Unlike other bats, the last cervical vertebra is not fused to the first thoracic vertebra. The second wing digit has a long supernumerary digit and a vestibular phalanx. The ischia are fused to each other and to the sacrum. The latter is keel-like.

The smaller bulldog bats are insectivorous, and while the larger bulldog bats also eat insects, their main diet is fish. They use echolocation to accurately determine the ripples they create on the surface of water.

The larger bulldog bat can fish on the water's surface with its long, curved claws about 2–3 cm below the surface. It makes a sweep of 30 cm to 3 m before ascending and turning its head to make the reverse sweep. In one night, the bat can catch 20–30 small fish in this way.

9. Kakapo Bird

The kakapo, also known as the owl parrot, is the loudest bird. The mating call of this New Zealand native can be as loud as 132 decibels. The nocturnal kakapo is the heaviest parrot in the world, weighing in at 4.85 pounds (2.2 kg) for males, and is also the longest-lived bird known, living to be 90 years old.

With its distinctive blue and fawn plumage, the kakapo is world-famous as the longest-lived and heaviest parrot in the world. The bird was also at risk of extinction before being successfully rehabilitated, with the population increasing from 50 in the 1990s to 213 today.

The Kakapo, also known as the “mighty moss chicken,” once lived all over New Zealand, but today it is found only on islands that have no predators. Males make loud noises to attract females, says Laura Keown, a spokeswoman for the Bird of the Year contest.

What makes this parrot species unique is that it cannot fly, possibly because its wings are too large to support it. Hence its nickname, the flightless parrot. As a nocturnal species, it forages and mates at night. This has led some places to call it the owl parrot because its habits are quite similar to owls.

10. Cicadas

Cicadas, also known as golden cicadas, are a superfamily of insects with large heads and two wings with many stripes. There are about 2,500 species of cicadas in the world, in both temperate and tropical regions. Cicadas are the most well-known insects because of their larger size, special shape with large heads and the ability to make a loud, rustling sound all summer long. In the Appalachian Mountains, Americans call cicadas dry flies because their shells remain intact and dry after molting. Of course, cicadas cannot be left out of this list because you have had sleepless summer days because of their chirping. There are two types of cicadas: green cicadas and yellow cicadas. Males of both species can make sounds up to 120 decibels, it sounds like they are screaming, right? But they do not use their mouths like we do when we are angry, it is the sound from their abdomens. Their abdominal calls are species-specific, so they do not attract females with whom they cannot mate.

Unlike other insects, such as crickets, which make sounds by rubbing their wings together, male cicadas make sounds by vibrating two "speakers" made of thin membranes, which develop from the thorax, with ribs inside. The ribs are stretched very quickly, vibrating the thin membrane, creating sound waves. The cicada's abdomen is hollow, so it can amplify the sound of the cicada's call very loudly. Cicadas shake their bodies and use their wings to create a rhythm for their "song". Each species of cicada has a different sound, intensity, and pitch - to attract female cicadas of the same species.

Female cicadas cannot make sounds, but they also have two membranes on their bodies, which are only used to "listen" to the male cicadas singing and to be lured. When not singing, male cicadas also use these two speakers as "ears" to listen to the surrounding movements. Some species of cicadas are capable of making sounds up to 120 dB, the loudest call of any insect.
