What sound waves do whales make, what kind of whales call

Ultrasound is likely, but I haven't heard of infrasound in whales.

The sound waves emitted by whales are the same as those produced by bats, which are ultrasound!!

The call of the dolphin is high-frequency, the blue whale is low-frequency, and the language system of the dolphin is more complex and perfect, and can express more meaning, while the voice of the blue whale is relatively large. But their cries are inaudible to humans. The blue whale's long whistling sound, which can last for half a minute or more, has a very low frequency of 188 decibels, making it the loudest known biological call so far.

The purpose of the blue whale's sound and its meaning is another mystery that experts on blue whales are most eager to unravel. The blue whale's call is incredibly high, even though most of its sound frequency is lower than what the human ear can hear. Through the recording facilities of the United States Navy listening and tracking submarines left over from the Cold War, scientists have found that listening posts in the Atlantic Ocean can detect the calls of blue whales from 3,200 kilometers away, and from the waters off Puerto Rico, they can even hear the calls of blue whales near Newfoundland.

An expert in the United States said: "The blue whale is the loudest animal on the planet. ”

Look at my hard mouth ooooo, I didn't just call it that.

The meaning of the whale's call: to indicate fear. Whales will make calls when they are underwater, in addition, whales will laugh very loudly when they are extremely frightened, and when whales are stranded, whales are very afraid in their hearts, because they are disconnected from the sea, and whales are not able to move on land, so whales will have very miserable calls, and people will be very frightened when they hear this tragic cry.

Among the groups of whales, the most singing whales are baleen whales. Sometimes they are sung in chorus, sometimes solo, and although they are played differently, they all sing the same song. But they usually only sing a song for one year, and the next year they get a new one.

The music of the whale is very complex, and there is a certain rhythm, just like the rhyme of human poetry, each line has the same ending, much like the aria in human classical music.

The whale's call has a quiet, ethereal feeling, which is why the whale's call is terrifying.

In fact, the whale's call is not particularly scary, the whale makes sounds through sonar. Sonar is much smaller than normal vocal cords, but the vibration frequency is large, and the amplitude of vibration is also greater than that of ordinary vocal cords, so the frequency and loudness of sonar are higher than those of the vocal cords.

And the whale's call is transmitted to the air through the water, because the medium of transmission changes in the middle of the way. Therefore, the whale's voice has a quiet, ethereal feeling, so this leads to the whale's cry is very terrifying.

The situation faced by whales

Whales do not have a single natural predator in the ocean, but whales have a deadly natural predator on land, which is humans. Over the course of hundreds of years, humans have over-captured whales, leading to the extinction of many species of whales.

Now that human beings have finally realized that whales are gradually decreasing, they have begun to adopt many policies, prohibiting whale fishing, and setting up a whale rescue team. Some whales are accidentally stranded during the procession, and the whale rescue team will take immediate action to release the stranded whales back into the sea, and humans will take good care of the whales.

The sound made by whales is called "whale sound" (no official definition), and the whale sound recorded by humans is called "whale song" or "whale language", and different cetaceans produce different sound methods. In any case, the sense of smell is useless due to the difficulty of seeing due to the absorption of light by water, and the slower flow of water compared to air.

As a result, all dolphins and toothed whales rely more on sound than their terrestrial counterparts for communication. The important and devastating effects on marine animals due to the large amount of environmental noise generated by human navigation have attracted the attention of environmentalists.

The whale's call is one of the loudest in the ocean, and it can even penetrate the earth's crust.

Echoes of whale calls recorded by instruments on the seabed** indicate that sound waves can penetrate sedimentary layers and the rocks below. The sounds can help probe the structure of the Earth's crust when traditional investigative methods are not available, researchers report in the Feb. 12 issue of Science.

Whale Profile:

Whales are one of the genus Baleen Whales in the family Baleen Whales, an IUCN endangered species, not only the largest cetacean, but also the largest mammal to date.

The confluence of warm water and icy water is an excellent habitat for blue whales, the icy waters are usually rich in plankton and krill, blue whales usually feed on these two creatures, blue whales are distributed worldwide, with the largest number of Antarctic seas, mainly temperate and cold cold waters with water temperature of 5-20, and a few whales have come to swim in the Yellow Sea and Taiwan waters.

The whale has a pale blue huitzer or rat gray on its entire body, with pale fine markings on its back, white spots on its chest, and its anterior lobble can be up to 33 meters long and weigh up to 181 tons.
