The Loudest Animals on Earth (And They’re Not Who You Think)

Sperm Whale Clicks — The Loudest Sound in the Animal Kingdom

When it comes to sound, the sperm whale is unmatched. These deep-sea giants produce clicks that can reach up to 233 decibels — louder than a jet engine at takeoff. These clicks are part of their echolocation system, used for navigating and hunting in the dark ocean depths.

Sperm whales emit these sounds in short bursts to locate prey, communicate with others, and map the underwater world. Despite their power, these sounds are highly directional, focusing the energy like an acoustic laser. If you were near one of these clicks underwater without protection, it could seriously damage your hearing or even injure tissue. They may not roar, but sperm whales are sonic titans of the sea.

Pistol Shrimp — The Underwater Sniper

This tiny creature — only about 5 cm long — holds a world record for the loudest noise per body size. The pistol shrimp creates an explosive snap with its specialized claw, generating bubbles that collapse at speeds of over 60 mph. This produces a shockwave reaching 210 decibels — enough to stun or kill nearby prey.

What’s more fascinating is that the collapse of the bubble produces a flash of heat close to the temperature of the sun’s surface, though it only lasts microseconds. This is one of the few times where sound becomes a weapon, making this shrimp one of the most dangerous animals at its size.

Howler Monkeys — The Loudest Land Mammals

High in the canopies of Central and South America, howler monkeys earn their name with roars that can travel up to 5 kilometers through dense jungle. At around 140 decibels, their calls are used to claim territory and warn rival groups to stay away.

Male howlers have an enlarged hyoid bone in their throats that acts like a resonating chamber, amplifying their calls. These vocalizations are so deep and powerful that they often shake the forest with sound, a phenomenon rarely found in non-human mammals. Despite their noise, howler monkeys are generally peaceful — it’s mostly sound bluffing to avoid fights.

Blue Whales — The Deep Singers

Blue whales are known for their deep, rumbling songs — low-frequency sounds that can travel across entire ocean basins. Their calls typically reach 188 decibels, although they sound quieter to human ears because of the low pitch.

These vocalizations help them locate mates, navigate long distances, and maintain contact across vast areas of open water. In ideal ocean conditions, a blue whale’s call can be heard by other whales up to 1,600 kilometers away. Their sound isn’t sudden or sharp like the sperm whale’s click, but in terms of endurance and distance, their voices dominate the sea.

Cicadas — The Noisy Insects of Summer

Cicadas are insects famous for their shrill, continuous calls during hot summer days. Some species, like the African cicada (Brevisana brevis), can produce sounds up to 106 decibels — equivalent to a chainsaw. What’s remarkable is that they do this using no lungs at all.

Male cicadas have structures called tymbals on their abdomens, which they vibrate rapidly to produce sound. Their hollow bodies act as amplifiers. These calls are meant to attract females, and some species sing in synchronized choruses, creating a wall of sound so intense it can overwhelm the ears of predators.

Northern Elephant Seals — The Roaring Beasts of the Beach

On coastal beaches during mating season, male elephant seals engage in loud vocal battles to compete for harems. Their booming grunts and roars, which reach up to 126 decibels, are broadcast through inflated nasal cavities that serve as natural echo chambers.

These sounds serve as both threats to rivals and signals to females, asserting dominance without needing constant physical fights. The noise often echoes across entire colonies, and the largest males with the deepest, loudest calls usually win breeding rights — proving that in the animal world, volume can mean power.

Bullfrogs — The Amphibian Amplifiers

Don’t let their size fool you — American bullfrogs can produce croaks up to 119 decibels. That’s louder than a typical rock concert. Their calls, mostly heard during mating season, are so powerful because of their resonating vocal sacs, which expand like balloons to broadcast their calls across ponds and wetlands.

Bullfrogs also use these sounds to establish territory and ward off rivals. Despite their peaceful appearance, bullfrogs are aggressive both vocally and physically, and their sound is a survival tool as much as a love song.

Community

In the animal kingdom, sound isn’t just noise — it’s a survival strategy. From the deafening clicks of sperm whales to the explosive snaps of pistol shrimp, nature has evolved creatures that use sound to hunt, communicate, and compete. Often, it’s the smallest or least expected animals that are the loudest.

These record-holding vocalists remind us that power doesn’t always roar — sometimes it clicks, grunts, snaps, or hums across oceans and forests. And just like us, animals use their voices to be heard, understood, and remembered.

If this article made you rethink which animals rule the wild with sound, share it with someone who still thinks lions are the loudest. Because the real noise-makers are out there — and they’re louder than you’d ever guess.
