How do bats use their ears to see ?

Bats use their ears to "see" things. It turns out that bat ears use ultrasound echolocation to sense the presence of objects. Normally, people can only hear sound waves that vibrate 16 times and 20,000 times per second, and more than 20,000 vibrations per second are inaudible to the human ear, so they are called ultrasound.

However, bats and some other animals can hear ultrasound. Bats use their characteristic larynx to produce powerful ultrasound waves that are emitted outwards through their mouths and nostrils. When the ultrasonic waves encounter an object, they are reflected back like light waves, and the sound waves emitted back are received by the ear.

The bat's ears are large, and the inner ear is particularly well developed, which can receive and resolve 250 sets of echoes in one second, and the resolution is very high. Bats judge the type, size, and distance of objects based on their echoes to distinguish whether they are food, enemies, or obstacles. Its echolocation also has a high anti-interference ability, a cave often has tens of trillions to hundreds of millions of bats inhabited, when they fly away or return to the cave, they have to make a call, these thousands of calls and the echo of the cave wall are intertwined, but can not interfere with each other, this resolution and anti-interference ability is any artificial sonar system can not be reached.

Of greatest interest to bats are anti-submarine specialists. In World War II, in order to deal with German submarines, the navies of Britain, the United States and other countries invented a hydrophone, mounted it on the **, and discovered the submarine by listening to the sound of the propeller of the underwater submarine. But when ** sails, its own propellers are loud, and the hydrophones can only hear the sound of the propellers on their own boat.

In order to avoid this interference, after a long period of exploration, sonar, that is, ultrasonic rangefinders, was invented, which made it possible to quickly calculate the location of enemy submarines. <>

There are more than 1,000 species of bats on Earth, and the most common ones we see are insectivorous bats. In the tropics, there are also bats that eat fruits, fish, and even suck the blood of animals and humans. No matter what kind of bat, they "see" with their ears.

It has a unique ultrasonic device on its mouth and nose, which can continuously emit high-frequency ultrasonic waves when flying, and when it hits obstacles or flying insects, it can be reflected back into an echo, and then received by the ears, according to the echo, the bat can determine the direction, identify food or obstacles, and effectively avoid or pursue. If the bat is blindfolded, it can still fly completely normally, but if the bat plugs its ears, it will hit walls everywhere when flying. <>

Because the eyes of bats are degraded, they need their mouths to emit their unique sound waves, and then use their ears to listen to the echoes of sound waves when they encounter something!

The bat always lives in the dark, and his eyes have deteriorated and he can't see anything clearly, so he uses the survival of the fittest. He evolved his mouth and ears and used the principle of ultrasound to distinguish the direction and position, which is better than the eye.

The throat of a bat can emit very strong ultrasound waves, (if a sound vibrates more than 20,000 times per second, the human ear cannot hear it, this is called ultrasound.) ) is emitted outwards through the mouth and nostrils. When an object is encountered, the ultrasound waves are reflected back and received by the bat's ears.

Bats judge the type, size, and distance of objects based on their echoes, distinguish between enemies, food, and obstacles, and then calmly decide whether to dodge or pursue.

When bats fly, they are able to produce ultrasound waves in their throats, which are emitted through their mouths. When ultrasound waves are reflected back when they encounter an insect or obstacle, bats are able to pick them up with their ears and can tell whether the target is an insect or an obstacle, and how far away it is.

People usually call this way of detecting targets in bats "echolocation". The signals emitted by bats as they seek food, orient themselves, and fly are made up of ultrasonic phonemes that resemble speech phonemes.

The bat must receive the echo and analyze the sound characteristics of the echo, such as amplitude, frequency, signal interval, etc., before deciding what action to take next. Bats that rely on echo ranging and localization emit only a simple sound signal, which is usually composed of one or two phonemes that appear repeatedly according to a certain pattern.

When a bat is flying, the signal is bounced back by the object, forming an echo with different sound characteristics depending on the nature of the object.

The bat then determines the nature and location of the object after analyzing the sound characteristics of the echo, such as frequency, pitch, and sound interval.

The bat itself has a hearing frequency higher than 20 kHz, which is higher than the hearing range of the human ear, and the ear constantly changes the direction of flight after receiving ultrasound waves.

The structure of a bat's ears determines its ability to hear ultrasound.

The throat of bats can emit strong ultrasound waves that are emitted through their mouths and nostrils, and the ultrasound waves are reflected back when they encounter objects.

Summary. Bat ears are a kind of hearing and balance organ of bats.

Bat ears are a kind of hearing and balance organ of bats.

Bats are nocturnal and only active at night. But their eyesight is very poor. So, how do they fly and find their prey?

Take advantage of their special auditory and echolocation systems. In fact, bats are the most sensitive auditory animals in the mammalian family. When bats fly at night, they make a series of calls.

Ultrasound, to be precise. Then, he used his sensitive ears to process the echoes that returned. There is a high concentration in the bat ear, which helps to identify the location and size of distant objects.

The bat (scientific name: chiroptera) is a class of animals under the phylum Mammal, and is the only animal that can truly fly. In addition to the characteristics of mammals in general, there are a range of morphological characteristics adapted to flight.

Summary. Hello, glad to answer for you. The role of bat ears is that the role of bat ears is to use sound waves and echoes to determine the position of objects in space.

Bats emit sound waves from their mouths or noses, and when the sound waves hit an object, they produce an echo, which is from the object** and returns to the bat's ears in order to judge the position, size, and shape of the object.

Bat. It is a class of animals under the phylum Chordates and Mammals, and is the only mammal that can truly fly; In addition to the characteristics of mammals in general, there are a series of morphological characteristics adapted to flight [1] . The smallest is a mixed bat, weighing only grams, with a wingspan of 16 cm; Some flying foxes can weigh more than kilograms and have a wingspan of up to meters.

Bats are light-boned, have a high degree of healing of the skull, well-developed shoulder girdles, and have keel-like protrusions on the sternum. Degeneration of the tibia and fibula of the hind limbs. The ear shell is well developed, often with a well-developed tragus or tragus.

There are abundant sensory hairs on the wing membranes, ears, lips, etc. The colors are varied, mostly brown, gray, and black. The earliest known bat fossil is the 50-million-year-old index finger Ishen bat, which was found in Wyoming, USA.

More complete fossilized bats were later found in the bed of Lake Maisel in Germany, which date back to the Eocene epoch and contain fossilized insects in their stomachs.

What do bat ears do.

Hello, I have seen your question and am sorting out the answer, please wait for a while Hello, I am happy to answer for you. The role of bat ears is that the role of bat ears is to use sound waves and echoes to determine the position of objects in space. Bats emit sound waves from their mouths or noses, and when the sound waves hit an object, they produce an anaechoic sound, and the echo is from the object** and returns to the bat's ears in order to judge the position, size, and shape of the object.
