Each of our five senses is more important and functional than the others. The absence or imperfection of anyone undoubtedly makes our lives very difficult. In fact, our organs have at this point form and structure show no random formation.

Now these folds that our ears have, Let’s see what features it offers when it comes to hearing skills..

Before we move on to answering this question, let’s talk about the parts of the ear and the role of each in processing sounds.

This structure; It consists of three parts: outer ear, middle ear and inner ear. occurs. Starting from the outer ear, the auricle is the visible part of the outer ear and is responsible for collecting sound waves. Again, the auricle sends sound waves to the ear canal (external auditory canal).

Vibrations of the eardrum in the middle ear activate the ossicles and these ossicles are known as the smallest bones in the human body. The three bones in this section are; malleus (hammer), incus (anvil) and stirrup are named according to their shape.

Also, the small ascending bone attaches to an oval window that connects the middle ear to the inner ear. Eustachian tube opens to the middle ear It balances the pressure between the air in the middle ear and the air outside the ear.

Finally, the sound waves enter the inner ear and then the cochlea, an organ that resembles a snail. This snail is filled with a fluid that moves in response to vibrations of the oval window and As the fluid is activated, approximately 25,000 nerve endings are activated.

In addition, nerve endings convert vibrations from the ear into electrical impulses to the brain. Brain too interprets these signals and the hearing process takes place in this way.

The part we will focus on is the outer ear.

The curved part of the ear is the outer ear, called the auricle or auricle. this structure extremely flexible and made of pliable skin and cartilage occurs. The auricle also has several parts such as tragus, spiral, lobule, and cone. Again, the outer ear continues from the auricle inward to the ear canal and the outer layer of the eardrum.

When it comes to perceiving sound waves, the auricle; collecting, amplifying and directing sound waves in the ear canal has a function. In addition, although it is a different part of the outer ear, the external auditory meatus, called the ear canal, also amplifies sound waves to some extent.

This wrinkled and curved structure of the auricle is not random.

The wrinkled and curved nature of the ear actually raises the pitch of the most common sounds we can hear. So this structure while reducing all other unnecessary sounds reaching our earsIt allows us to hear what we need to hear in a healthy way.

In addition, the way the sound waves interact with the auricle, distance, direction and height of the incoming sound source It passes on the necessary clues about this to our brain.

So what would happen if our ears were much bigger? Can we hear the voices better?

The ears of elephants, for example, are many times larger than ours, but this size has little to do with hearing. These animals fan their ears to cool down, and the large surface area of ​​their ears allows them to avoid heat.

In other words, it would be a very wrong idea that big ears have a positive effect on hearing. In short, our ears, which have a very complex structure, This wrinkled and curved structure allows us to perceive the sound in the clearest way.
