Which Animal Produces the Loudest Sound?
From Ocean Clicks to a Snapping Claw, Nature’s Loudest Noises Come From Unexpected Places
The “loudest animal” title depends heavily on how you measure sound. If you’re talking about raw acoustic pressure underwater, the sperm whale‘s echolocation clicks are often cited as the loudest sounds produced by any animal. But if you measure the sharp, sudden snap of a claw, the tiny pistol shrimp briefly produces a shockwave loud enough to momentarily outshine a gunshot at close range. Neither of these record-holders is what most people picture when they imagine a “loud animal” — and that’s part of what makes this topic so interesting.
💡 Quick Fact
This guide compares several genuine loudness record-holders, explains how sound measurement actually works underwater versus in air, and clears up a few common myths.
Why Comparing Loudness Is Tricky
Sound is measured in decibels, but decibel scales work differently underwater than in air, and a sound’s loudness also depends on how close you are to the source. That’s part of why different sources sometimes name different animals as the “loudest” — the answer shifts depending on measurement method, medium, and distance.
Underwater Record
The sperm whale’s clicks top most measured lists
Sharpest Shockwave
The pistol shrimp’s snap briefly rivals a gunshot
Loudest on Land
The blue whale still wins by combined power and range
Decibel measurements underwater use a different reference pressure than measurements in air, so a fair, direct comparison between an ocean sound and a land sound requires careful conversion, not a simple side-by-side number.

The Genuine Loudness Record-Holders
These species are consistently cited by researchers as producing some of the most extreme sounds in the animal kingdom, each in a different way:
A sperm whale’s echolocation clicks are often cited as the loudest sounds produced by any animal, generated to hunt giant squid in total darkness at extreme depths.
This small shrimp snaps a specialized claw so fast it creates a collapsing air bubble that briefly produces heat, light, and a shockwave loud enough to stun small prey.
While not quite as intense at the source as a sperm whale’s clicks, blue whale calls are low-frequency and powerful enough to travel across entire ocean basins.
Other Remarkably Loud Animals
Beyond the top record-holders, several other animals produce sounds that are extreme in their own specific way:
🎯 Explore Another Notably Loud Animal
Howler monkeys are often cited as the loudest land animal relative to their size, with calls audible from several kilometers away through dense rainforest.
Certain African cicada species are considered the loudest insects on Earth, producing calls loud enough to cause discomfort at close range.
The Eurasian bittern produces one of the loudest bird calls in the world, a deep, booming sound audible from several kilometers away across open wetland.
Myths vs. Facts
Even a fun topic like this comes with a few common misconceptions. Let’s clear up some of the most frequent myths:
🏆 “There’s one single, universally agreed ‘loudest animal’ record”
The answer genuinely depends on the medium (air vs. water), whether you measure at the source or from a distance, and what counts as “loud” in the first place.
🦁 “Lions have the loudest roar of any land animal”
While impressively loud and audible for kilometers, a lion’s roar is not considered the loudest land animal sound; howler monkeys and some other species are typically cited as louder relative to size.
🐋 “A blue whale’s call would deafen a nearby diver instantly”
While extremely loud, the low frequency of blue whale calls means they’re felt as much as heard, and the reported decibel figures reflect intensity at the source, not the direct experience of a nearby swimmer.
Compare by Purpose
Different animals evolved loud sounds to solve very different problems. Pick a purpose to explore:
Conclusion: Loudness Depends on the Question You’re Asking
“Loudest animal” isn’t really a single competition — it’s several different ones, each measuring something slightly different: raw intensity at the source, distance traveled, or sheer surprising force relative to body size. Whether it’s a sperm whale hunting in total darkness or a tiny shrimp collapsing a bubble hot enough to briefly glow, the animal kingdom’s loudest sounds are almost always in service of a very specific survival need.
