Features of the cat’s ear
Ear structure
The cat’s outer ear consists of the ear wing, the outer ear flap and the outer ear canal.
The outer ear flap is also called Henry’s pocket. It has a pocket-like opening, which has a certain function of filtering and amplifying the signal, which can enhance the perception of high-frequency sounds, and even has the effect of jet lag. The sound that was previously extinguished.
The middle ear includes: tympanic chamber, tympanic membrane, mastoid and ossicular chain.
The inner ear includes: semicircular canals, vestibule, and cochlea.
The semi-circular vestibule of the cat is filled with vestibular fluid and is lined with tiny hairs. The movement of the fluid on the hair allows the cat to accurately perceive and feed back the direction of acceleration and deceleration to the brain.
It can make the cat prepare to judge the position and orientation, and play an important role in adjusting the posture and maintaining the balance of the cat.
Of course, this also causes cats, like humans, to experience motion sickness (motion sickness, seasickness) caused by inconsistency between motor system feedback and brain experience.
Auricular muscle development
Cat ears have 32 muscles, while humans have only 6, and cats have left ear And the right ear can be rotated 180 degrees independently, which makes it easier for cats to collect sound waves and increase the range of hearing monitoring.
Cats have a strong ability to locate sounds. Different cats can distinguish two different sound sources that are 15~29 meters away from it and 1 meter apart from each other. They can test the cat Sanxiangui Cave from a long distance. The cat can accurately know the exact position of the fairy ball, provided that the Cats can play this game.
Hearing Threshold Range
The range of sounds that humans can hear is about 16-20K Hz. Cats can hear low-frequency sounds of 20-45 Hz, and their bass ability is slightly inferior to that of humans.
However, cats’ ability to hear high-frequency sounds is not only much stronger than humans, but also much stronger than dogs. We call sounds higher than 20K Hz as ultrasound. Cats can distinguish sounds of up to 78K Hz, and the high-frequency capability is about 4 times that of humans and about 2-1.5 times that of dogs.
Cat ear posture
There are many kinds of cat ear postures, there are about 5 common postures, which can be Straight or close to the head, you can turn or shake.

The cat turns its ears, indicating that it is listening to some subtle sounds around, observe the cat’s eyes, if It is a casual state, indicating that it is still relaxed, and it may just be an accident.
If you suddenly stare in a certain direction, and your ears keep turning, it means that it is alerted that there may be prey or intruders there.
Airplane Ears
When cats sense danger, their ears curl up to make them look smaller, and they usually lie flat back and close to their heads.
Usually the cat does something wrong, and when you come over, the cat may have this reaction.
At this point, the cat is anxious and wants to run away. If you stop it, it may attack you.
You need to observe the direction of the cat’s airplane ear. If the airplane ear is close to the head, it means that the cat has accepted it. If the airplane ear is inclined upward, the cat may resist and prepare to fight.
