Blue whale is a marine mammal, belonging to the suborder baleen whales, with four subspecies. It has strong adaptability and can survive in water at about 5-20℃. It is distributed in the four oceans of the world. In fact, the blue whale is not only the largest animal, but also the loudest animal.

Although we have never heard the sound of blue whales, the low-frequency sound that blue whales use to communicate with their partners can be described as deafening. Measure the sound, which is as high as 188 decibels, which is louder than the sound made by a jet plane parked beside the runway when it takes off.

2. Big Wolf

Gray wolf is the largest subfamily of wolves, which has absolute dominance in Eurasia and many places in North America. Wolf howl is one of the most famous howls in the world. Their howling can reach 90 decibels to 1 15 decibels. Every full moon night, wolves will make a melodious cry, which makes people feel numb and their hearts beat faster.

The voice of a tiger is lower than that of a lion, so the decibel is slightly lower, about 1 10 decibel. In addition, the living environment is mostly high mountains and dense forests, so the transmission distance is about 3 kilometers. Although the tiger's roar is lower in decibels, its deterrence is not bad at all. Birds and animals in the forest are often afraid to run for their lives. As the saying goes, the tiger roars in the mountains, and the beasts are surprised, and the gloomy clouds are bleak and Wan Li condenses.

Step 3: hyenas

Hyenas, known as the second brother in Africa, are the most powerful society in Africa except lions. They are cruel, ambitious and always want to be the boss, so they often have fierce conflicts with lions.

Before hyenas fight, the leader will also communicate with his family by barking, and the barking sound is as high as112dB. They can express different meanings by making different sounds. With this kind of "hyena language", whether fighting or hunting, it is even more powerful.

4. the lion

Although the hyena's voice is loud, it is still a bit inferior to the roar of African lions. Lions are the second largest cat in the world and the largest carnivore in Africa. Although often challenged by the second brother, no one can shake the position of the first brother.

When a lion roars, it can make a sound as high as 1 10 to 120 decibels, which can reach at least 5 kilometers on the vast grassland. In addition to scaring restless people around, the lion's roar is also a way to swear territorial rights. Intruders can know the strength of the owner here by judging the sound quality of the lion's voice.

5.tiger

Tigers are the largest cats in the world and the top carnivores in the Asian continent. Like a lion, a tiger will roar loudly. When provoked, tigers will make terrible growls during mating season or hunting.

The voice of a tiger is lower than that of a lion, so the decibel is slightly lower, about 1 10 decibel. In addition, the living environment is mostly high mountains and dense forests, so the transmission distance is about 3 kilometers. Although the tiger's roar is lower in decibels, its deterrence is not bad at all. Birds and animals in the forest are often afraid to run for their lives. As the saying goes, the tiger roars in the mountains, and the beasts are surprised, and the gloomy clouds are bleak and Wan Li condenses.
