This is a question that many people wonder about. Most people think that the auricle is just a structure that helps you wear accessories, such as masks, glasses, hearing aids, etc. However, that is only partly true. In fact, the auricle also helps your hearing to be more sensitive.
The reason the auricle has a concave-convex structure is to create folds that help receive and absorb sound waves. Thanks to that, your ears can hear better. In fact, without the auricle, it will be very difficult to distinguish the location of the sound, the direction of the sound and distinguish between one sound and another.
In addition, the auricle also plays an aesthetic role. A beautiful auricle also helps your face to be more balanced and vibrant.
