According to BBC, the sperm whale is perceived to be louder than the blue whale. A blue whale's call is 20 Hz and a sperm whale's click is about 10,000 Hz. The sperm whale registers at 230 dB while the blue whale is at 188 dB.
The title for loudest animal on Earth is typically awarded to the blue whale, according to BBC. Though blue whales still hold the title for largest animal, the 188 decibels of their calls have been trumped by another aquatic mammal: the sperm whale, which can emit a click that soars to 230 decibels.
The loudest animal sound ever measured in decibels is the sperm whale (230 dB). However, the loudest animal ever to be recorded is the lesser water boatman. It is a minuscule insect that can generate mating calls as loud as 99.2 dB.
The sperm whale, capable of producing clicking sounds up to 233 decibels, is the loudest animal in the world. That's not the only category it leads. The sperm whale is also the largest toothed whale on earth and has a larger brain than any other animal.
Their clicks can be as short as 1/1000 of a second, and their range goes all the way up to their 'gunshot', one of the most powerful sounds on the planet – as loud as 230 decibels. To put this into perspective, a jet taking off registers at around 150 decibels from 25 metres, enough to rupture an eardrum.
Blue whales make an extremely loud whistling call to each other. These noises are known as sirens and these can reach up to 188 dB which is louder than a jet engine or a grenade explosion. Sound carries further under water, so the whales can be heard up to 800km away.
Despite being known as gentle giants, blue whales can emit sounds loud enough to cause hearing loss in humans. These massive creatures can make noises as loud as 188 decibels, which is 38 decibels higher than a jet taking off 25 meters away.

The blue whale, the largest animal on earth, can produce loud whistling calls that reach up to 188 db. These calls can travel up to 500 miles underwater. But the loudest is the sperm whale. It makes a series of clicking noises that can reach as high as 230 db making it the loudest animal in the world.
Not only can baleen whales emit calls that travel farther than any other voice in the animal kingdom, these giants of the deep also create the loudest vocalisations of any creature on earth: the call of a blue whale can reach 180 decibels – as loud as a jet plane, a world record.
While blue whales are both the loudest and the largest animals, the sperm whale is louder in terms of pure decibels. Its clicks are measured at an incredible 230 decibels.
Gray whales are known to be very curious and inquisitive, giving them reputation of being the “friendly” whale. They often swim right up to boats and poke their heads vertically out of the water to get a better view of their surroundings in a behavior called spyhopping.
A sea creature less than 2 inches long is one of the ocean's loudest creatures, and research has found that it may only get louder as a result of the oceans getting warmer. The "snapping shrimp" – also known as the pistol shrimp – is notable for its massive claw, which is about half the size of its entire body.
Orcas take down a blue whale, proving they're the apex predators of the ocean. While killer whales are known to attack blue whales, John Totterdell and his colleagues are the first to ever document a successful takedown. And they've done it more than once, publishing their findings in the journal Marine Mammal Science.
Blue whales can make extremely loud whistling calls each other. Their sirens can reach 188dB, louder than jet engine or grenade explosion. Sound carries further underwater, so the whales can be heard over 800km away.
Because of their size, power and speed, adult blue whales have virtually no natural ocean predators. The only sea creature known to attack blue whales is the orca whale (scientific name: Orcinus orca) also known as the “killer whale”. They have been known to work in groups to attack blue whales.
Sperm whales carry the largest and one of the most complicated biological sound generators in the animal kingdom. Their sound generating nose can reach a weight of more than 10 tonnes and generate the highest sound pressures ever measured from any animal with back calculated source sound pressure levels of 230 dB re.
They are named after the waxy substance—spermaceti—found in their heads. The spermaceti is an oil sac that helps the whales focus sound. Spermaceti was used in oil lamps, lubricants, and candles.
The Gulf corvina is a species of croaker (so named for their signature sound) that dwells in the waters of the Gulf of California and the Colorado River delta. Every year between February and June, adults Gulf Corvina migrate to a 12-mile stretch of the Colorado River delta, where they breed in murky waters.
One of the most surprising cat facts is that cats can actually make almost 100 different sounds. From the peeps of kittens to the meows of adults, cats have a wide range of vocalizations.
Sperm whales are relatively placid mammals and very few incidents in modern times suggest otherwise. They mainly feed on squid and rarely attack, apparently only when mistaking other mammals for seals or prey.
Dominica, Caribbean Sea
Worthy of note are its marine environments, which are of particular interest for scuba divers. It's possible to do both whale watching and swimming with sperm whales nearby.
You Should Never Touch a Whale
You might get hurt or sick. Whales may scratch, bite, or thrash their tails, placing you in danger. Whales can also transmit a specific disease called brucellosis. You may also transmit bacteria to the whale, making them sick.
Blue whales produce stereotyped calls throughout the year. These calls have been described as pulses, grunts, groans, and moans, and are typically in the 15-40 Hz range, often below the threshold of human hearing.
The range of frequencies that whales use are from 30 Hertz (Hz) to about 8,000 Hz, (8 kHZ). Humans can only hear part of the whales' songs. We aren't able to hear the lowest of the whale frequencies. Humans hear low frequency sounds starting at about 100 Hz.
