Top 9 Loudest Animals on Earth That Can Rival a Jet Engine

There are animals whose sounds are so profound that they can travel thousands of miles. In fact, some whale shrieks can be so intense that they could rival a jet engine. Our world is home to such an astonishing array of creatures that push the boundaries of sound and transform our planet into a vibrant, albeit sometimes deafening symphony. The loudest animals on Earth use it for communication, navigation, and survival in a way that highlights the incredible diversity of life. These sounds also play crucial roles in sustaining their ecosystem. 

List of Loudest Animals on Earth

First and foremost, let us quickly take a look at the list of the world’s loudest animals and then understand their incredible sound capabilities one by one:

What Makes Them the Loudest Animals in the World?

Although the title of the world’s loudest animal often goes to the colossal inhabitants of our ocean. Scientists believe that the ocean is where the sound travels faster than the air. But land animals have also a fair share in this list. So let’s understand why are they so noisy; not literally, and what makes them the loudest. 

1. Blue Whale

The blue whale, the largest animal on Earth, is also arguably the loudest. Its low-frequency calls can reach an astounding 188 to 191 decibels, which is louder than a jet engine at takeoff. These powerful vocalizations can travel for hundreds, even thousands, of miles underwater, enabling communication across vast oceanic distances. They primarily use these deep moans and pulses for navigating, attracting mates, and perhaps even coordinating group movements.

2. Sperm Whale

While the blue whale's sustained calls are incredibly loud, the sperm whale produces the most intense singular sounds on the planet. Their rapid, repetitive clicks can reach an ear-shattering 230 decibels. These aren't just idle noises; sperm whales use these powerful clicks for echolocation, creating a sonar system that allows them to hunt giant squid and other prey in the inky blackness of the deep ocean. The clicks are incredibly short-lived but pack immense power.

3. Fin Whales and Bowhead Whales

The fin whale, the second-largest whale, produces low-frequency calls of around 189 decibels, also traveling hundreds of miles. Bowhead whales contribute to the marine symphony with complex songs reaching up to 189 decibels, vital for communication during their epic Arctic migrations.

4. Snapping Shrimp

Don't let their size fool you. The Synalpheus pinkfloydi (Snapping Shrimp) and Tiger Pistol Shrimp create one of the loudest non-whale sounds in the ocean. By rapidly closing a specialized claw, they generate a high-pressure bubble that implodes, producing a shockwave of over 210 decibels. This powerful snap is used to stun or kill their prey.

5. Howler Monkeys

Despite their relatively small size, howler monkeys live up to their name with roars that can reach 140 decibels. These low-pitched calls are used to mark territory and communicate with their troops, echoing through the dense jungle canopy. Interestingly, studies have shown a correlation between the loudness of their roar and the size of their testes, hinting at evolutionary trade-offs.

6. White Bellbird

Found in the Amazon rainforest, the white bellbird holds the record for the loudest bird call, with males belting out calls of up to 125 decibels to attract mates. This sound is comparable to a rock concert and is delivered with such intensity that it can be a challenge for potential partners to endure at close range.

7. Lion

The iconic roar of a lion can reach 114 decibels and be heard up to 5 miles away. This powerful vocalization serves multiple purposes: asserting dominance, communicating with pride members, and deterring rivals from their territory. It's a true symbol of the wild's raw power.

8. Cicadas

The male cicada, particularly species like the greengrocer, uses a drum-like exoskeleton on its abdomen to produce calls up to 120 decibels. These loud, buzzing sounds are primarily mating calls, a ubiquitous part of summer soundscapes in many regions.

9. Water Boatman

One of the most surprising entries is the water boatman, a tiny insect just 2 millimeters long. It produces sounds up to 99.2 decibels by rubbing its reproductive organs against its abdomen, making it the loudest animal relative to its body size. This underwater serenade is primarily for attracting mates.

The animal kingdom offers a profound lesson in the power and purpose of sound. Their vocalizations often far exceed the human pain threshold. As we continue to explore and understand these auditory marvels, it reinforces the critical need for conservation efforts to protect their habitats and preserve the natural soundscapes that are so vital to their existence, especially for marine species facing increasing noise pollution.
