Loudest Animals on Earth with Sounds. Can You Guess the Louder One?


No! Your wife is not the loudest one. 😂

While most of the animals in the world rely heavily on being in stealth mode or being absolutely quiet to hide and safeguard themselves from predators, there are a few who stand at the extreme end of the spectrum. These are the animals that make exceptionally loud sounds, and they do so to defend their territory, attract females for mating, find other animals in their group, or warn their companions of lurking danger.

Such high is the sound levels that humans will not be able to stand most of them. In fact, some of these sounds are far beyond the human hearing range. As most human conversations happen at 50 decibels, the human ear drums are designed to rupture at about 200 decibels.

Do you know which is the loudest animal on earth?

Well, brace yourself because you are about to find that out. In fact, we have enlisted 11 animals known for the loudest sounds on this planet!

Here are the world’s 11 loudest animals:

#1 North American Bullfrog

Mostly heard at: central Florida

It might be surprising to find something as small as a frog in the list, but the North American Bullfrogs are famous, or rather infamous for their loud screams that can go up to 119 decibels.

Usually, the bullfrogs make a number of sounds in different situations, and their loudest is a distress call that they make with an open mouth (they make the rest of the sounds with a closed mouth).

Apart from that, bullfrogs make a low, growling sound when they are caught and are struggling to cut loose. They make a grinding kind of a sound when communicating with each other.

When another male tries to trespass a territory, the male frog will make a short and sharp call as a warning sign. Their mating sound is referred to as an advertisement call, that even females make in some cases.

#2 African Cicadas

Mostly heard at: Gauteng, Mpumalanga, Northern Province and Kwazulu-Natal.

It is believed that there are around 3600 species of African Cicadas and scientists are still discovering more of them every year. While all of them are believed to be very loud, the trophy for the loudest insect goes to the Green Grocer and the next one to Yellow Monday.

These tiny insects make sounds that can range up to 120 decibels and can be heard as far as 1.5 miles away. Hence, it doesn’t come as a surprise that they are known as one of the loudest sound producing insects in the world.

But only male cicadas make this sound to attract mates. 🪰

Cicadas are unique in the insect kingdom as they have special body parts in their abdomen called the tymbals and they use muscles from their entire body to contract and make this loud sound.         

#3 Lion

Mostly heard at: Africa

The king of the jungle can have the rest of the animals in his territory shiver in fear with his loud and strong roars, that can be heard from 5 miles.

The Northern Elephant Seals are unique in the most striking way. They are believed to be the only animals in the world who make decisions based on their individual vocalization.

Every individual seal is believed to have a unique sound and each rookery (where a group of seals resides) has its own language.

It is based on this language that males challenge and fight over territory and win over the females. The males are the loudest and when they fight for the territory or win over a mate, their voice can reach up to 126 decibels. Female seals are known to produce louder sounds when they are in distress or sense danger for their young ones.

Elephant seals make loud sounds both on land and inside the water, but it is on the land when they are the loudest.

#5 Moluccan Cockatoo

Mostly heard at: Eastern Indonesia

Moluccan Cockatoos can be so loud that their sound is compared to be as high as a 747 jet. When at its highest, their scream can go up to 129 decibels, a lot for a bird of that size.

They are believed to make such high decibel sounds either when they sense danger or when they are bored (yes, you heard it right!) categorizing them as the loudest bird!

#6 Kakapos

Mostly heard at: New Zealand

One of the loudest species, and surely the rarest one on this list is the Kakapos parrot.

Loudest sound of Kakapos
Have you heard the sound of a Kakapos before?

It is the biggest in size in the parrot family and is a flightless bird that was on the verge of extinction in the 2000s. However, herculean efforts were made by the scientists to save this species that is only found in the islands near New Zealand.

Their numbers had fallen to only 84 adult birds in 2000 when a team of scientists relocated them to another, safer island and protected their existence. In 2020, their number had risen to 211 adult birds. The reason for such a low number is that these birds breed once in 4-5 years and they don’t start mating till they are 4 years old.

But it is during the mating season when the male Kakapos make this loud sound that can go up to 132 decibels. The males typically make loud mating calls – 20-30 sonic-like sounds that are followed by a metallic-sounding ching. This mating call can last up to 8 hours.  

#7 Howler Monkey

Mostly heard at: Southern Brazil, Paraguay, Eastern Bolivia

The entire forest area can echo with howler monkey sounds if they start howling in groups. Their sound can go up to 140 decibels and how loud their sound gets depends on different factors.

Firstly, if the environment supports echoes, the howls of the howler monkeys are exceptionally loud.

Secondly, if a male senses that a female is attracted to him, the howling gets even louder.

Thirdly, if two males are competing with each other – either for territory or a mate – they produce louder sound.

#8 Greater Bulldog Bat

Mostly heard at: Caribbean islands, Mexico, and Northern Argentina

Bats, that usually remain hidden through the day and get active at night might be the last option coming to our mind when we think of the loudest animals in the world, but unlike other smaller bats, greater bulldog bats can screech up to 140 decibels. This helps them navigate through the caves and locate fishes and other prey.

Their collective screeches are louder than a rock concert. In fact, the greater bulldog bat is believed to have the highest frequency among all other species of bats.

#9 Blue Whales

Mostly heard at: all oceans except the Arctic

Blue Whales are the biggest living mammals on Earth, so it is no surprise that their sound is also one of the loudest in the animal kingdom. Their vocalization isn’t just one of the loudest, but also travels the farthest than any other animal sound on earth.

When in the loudest, the voice of a blue whale can go up to 180 decibels, as loud as a jet plane. The uniqueness of their vocalization doesn’t stop there.

They make the longest-lasting calls, usually done during the mating season. The humpback blue whale males sing their unique songs where each session can last anywhere between 30 minutes to 23 hours.

#10 Mantis Shrimp

Mostly heard at: Indian and Pacific Oceans

We know you would shriek in disbelief that an insect as small as a Mantis Shrimp can be featured in a list that has other contenders like the Blue Whale. But, it is true. These tiny creatures living in the tropical and temperate seas have a unique claw that they use to catch prey.

It is the speed and clapping of the claw that creates a shrill, popping sound that can go up to 200 decibels. When they shut their claws, a giant air bubble is created that also creates a sharp spark distracting the prey.

#11 Sperm Whale is the loudest animal

Mostly heard at: Arctic and Antarctic Oceans

The sperm whale is considered to be the loudest animal in the world. They are capable of producing a clicking-like sound that can go up to 233 decibels. They make these sounds by forcing air through their nostrils that run by a number of air-filled sacs.

They have a unique body feature known as the monkey lip that clamps shut as the air continues to move through the sacs.

This sound then passes through their brain (sperm whales have the largest brain in the entire animal kingdom) that amplifies it further before the sound finally leaves their body. The result is such a loud sound that it can be heard from miles away.
