The planet’s loudest creatures howl, snap, roar and call when they are seeking out food. They also do this to look for mates or simply attempting to locate the way home. In nature, there is a whale that is louder than a jet plane’s engine and a shrimp with the ability to knock out prey with sound. There is also a monkey that could be heard afar as three miles in the distance. We have highlighted a few of these animals that could be located in the skies, in the seas, or on land.
The Blue Whale
This creature is considered to be the biggest animal that ever lived on this planet. It also has a massive call to accompany its massive size. The call of a blue whale can reach up to 188 decibels. That is louder than the roar of the engine from a jet plane at an ear-piercing 140 decibels. The blue whale is known to make moans, groans, and pulses which could be heard as far as 1,000 miles away. Scientists have discovered that blue whales have been reducing the frequency of their calls over the last decade or so. The reason for this could be ocean noise, warmer waters, and climate change.
This crustacean can be mainly found in the oyster reefs and coral reefs. They are also known as pistol shrimp and they stun their prey by closing the bigger of the two claws. They do this at a speed of roughly 62 miles per hour. This closing action creates a giant air bubble which makes a loud snapping sound when it pops. The sound can be as loud as 200 decibels, which is enough to knock out or at times kill the prey of the shrimp, depending on the size.
This primate received its name because of the clearly identifiable cries it makes. Howler monkeys are the biggest of all monkeys in the new world. When numerous howler monkeys begin to yell at dusk or at dawn, their sounds can be heard three miles away. The male species of the howler monkey have huge throats and vocal chambers that are shell-shaped. This provides them with the perfect anatomy for a loud sound. The howls from the monkeys have been documented at 140 decibels.
As bats forage and navigate for food, they create high-pitched echoes and calls. This system known as echolocation assists them, however, only for a relatively short distance. Scientists discovered that bats with calls at higher frequencies would cover bigger distances with louder calls. A study conducted in 2008 discovered that the greater bulldog and lesser bulldog bats reach decibels of 140 and 137 respectively. Bats also make low-pitched calls to allow other bats to pick up on their location in order to avoid collisions as they hunt.
This is the planet’s largest and also loudest parrot. The parrot is considered critically endangered and has a variety in its vocabulary, which includes braying and squawking sounds. The male species of the kakapo releases a noise similar to a sonic boom during the season of mating. Once the initial sonic booms are released, there is an aching call that is very high-pitched and metallic. The initial loud booms could reach decibels of 132. The pattern of the booms and chings could continue for more than eight hours each night, for roughly two to three months.
The king of the jungle could be quite intimidating especially when it roars. In 2011 a study was conducted and scientists discovered that these large cats carry square, flat focal folds. For comparison, most other animals and humans have triangular folds or vocal cords. The folds are quite fatty and elastic, permitting them to be flexible and strong while they vibrate. The lion could roar as loud as 114 decibels. These roars are normally as long as ninety seconds.
A rediscovered species of bushcricket has a calling song that is as noisy as a chainsaw. The sound is produced by the male species in order to attract females. Scientists discovered that the male katybid sings at roughly 74 kHz, utilizing stridulation. This process is completed where one wing acts as a scraper that rubs along a row of grooves that resemble teeth. It could also be rubbed against the other wing. This movement leads to a high sound level of approximately 110 decibels.
This is a nocturnal bird, referred to as the guacharo in South America, which is its native home. This bird utilizes echolocation in order to find the way in its dark cave, it calls home. In many studies, scientists measured their clicks at decibels as high as 100. In contrast to bat calls, the oilbird’s calls are well within the range of human hearing. These could become deafening when massive groups of birds come home in order to roost.
Common Coqui Frog
These are tiny tree frogs which are named after the loud sound the male species makes, that sounds like ‘ko-kee’. Males often reply to the first section of the call, while the females are attracted to the second part. The frogs are an issue in Hawaii, where there are no known natural predators. The population of the frogs has reached numbers in excess of 10,000 per acre in several areas. The calls can be as loud as 90 decibels, similar to the sound of a lawnmower. This has resulted in restless nights for those in close proximity.
