If you think some people are too noisy then wait till you read about some of the loudest animals in the world. A normal human shout is around 70 decibels. Anything above 120 decibels and it becomes physically painful. There are many animals, birds and even insects that can make much louder sounds than that. Sometimes animals use these sounds as mating songs while at other times they use them to scare away rivals. Whatever be the reason, when it comes to making a racket, these animals top the list…

5. Kakapo: 132db

4. Green Grocer Cicada: 135db
Cicadas are the loudest insects. They sing to attract mates and their noise can reach in excess of 135 db and travel for over a mile.

3. Bulldog Bat: 140db
Bats use sound to navigate in what is known as echolocation. Bulldog bats produce the loudest sounds among bats and can reach the level of 140 db.

Their sound is not audible to humans as it is in the ultrasonic range reaching from 20 KHz to 200 KHz.
2. Tiger Pistol Shrimp: 200db
Tiger pistol shrimp are a unique and interesting animal. Found in the Mediterranean, they have a claw that shoots jets of water at very high speeds. The speed is high that it creates an air bubble. When the bubble implodes it creates a shock wave that kills any fish in the range of 2 meters. It also creates a sound of about 200 db which is louder than a gunshot. The implosion of the bubble also creates temperatures at its center as high as that of the sun which cause a flash of light to appear each time this shrimp shoots his pistol.
1. Whales: 230db
Whales are known for their songs. 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. The click lasts for only 15 to 30 milliseconds and can stay audible to a sperm whale as much as 10 miles away.
