What is the loudest animal in the world?
Are you exposed to high noise levels in your everyday life? Maybe you live in the city and know very well what noise means.
Did you know that a lawnmower causes a noise level of around 70 dB? The horn of a car reaches even about 90 dB. An ambulance that drives past you is even louder with up to 120 dB. And if a jet jet starts next to you on a wheelfield, you'll be exposed to more than 130 dB.
In your everyday life, you also move in a strong and permanent noise backdrop and are confronted with noise from different sources and in different strengths. And what about your professional environment? However, there are other areas in which it can go loud.
Water, for example, has a higher density than air, so the sound waves also behave a bit differently. This results in a higher volume. Indeed, the loudest animals in the world live in the water.
Down in the water
You should not underestimate the volume of the underwater world. Here, for example, there is the so-called gun cancer, which reaches just a size of 5 cm. This little cancer produces a bang with a volume of more than 220 dB, making it actually the loudest animal in the world. It belongs to the shrimp-like animals and lives mainly in subtropical and tropical waters. His scissors use cancer as weapons that serve him as vital tools for survival. These scissors work like a turret. The cancer can fold it back in less than a single millisecond. This creates a pressure wave with bubbles that are as hot as the sun. You can reach temperatures of up to 4700 ° C. With this, the cancer can immediately disable its victim.
Do you know that a sperm whale with its call sounds reaches a decibel strength of up to 200? The sperm whale is thus the second loudest animal in the world. He agrees on click sounds. These sounds serve to communicate with the peers. In addition, the pottwal can orient itself with it or also detect potential prey animals. It sends out clicking noises and waits for the echo. This makes it possible for him to find out where prey animals are in his vicinity. One to two clicks per second are delivered from the sperm whale. A typical victim for a potty whale is a squid. Once the sperm whale has located its prey, it can even deliver up to 200 clicks a second.
The blue whale is the third loudest animal on earth. At the same time, the blue whale is also considered the largest and heaviest living being in the world. In addition, it can reach the considerable volume of up to 188 dB, and that is achieved by the blue whale with its vocals. This can still be heard up to a distance of more than 850 km. The voice of the blue whale extends even further. He takes noises from wide distances of up to 1600 km was.
What man cannot hear
Noise of 160 dB can already damage your eardrum. Do you know why you will not be deaf to the loud and shrill sounds of the animals? Because the frequencies are different, you don't take them as human beings at all. There are a lot of animal sounds you can't hear at all. As a human, you can only perceive frequencies in the areas 20-20,000 Hz. For example, you will never be able to decipher the language of the elephants. Elephants talk at frequencies of less than 20 Hz, i.e. they lie outside the frequency range audible to humans. We are talking about sounds produced by infrasound. The call of the bat works very similarly. You can't even hear it in its full range. Bats communicate at frequencies of up to 100,000 Hz, so these tones are too high for human hearing and therefore not perceptible.
