The ears are the organs that capture sound waves to be experienced as sound by the brain. Along with the eyes, nose, and mouth, the ears are the specialized senses of humans.
Parts of the Ear
The ears are broadly divided into three parts:
- The Outer Ear, Which Consists of the Pinna and the Ear Canal. This Part is Commonly Referred to as "the Ear," but It is Actually Only One of the Three Parts of the Ear. This Part Leads Sound Into the Middle Ear.
- The Middle Ear, Which Consists of Three Tiny Bones That Pick up and Transmit Sound Vibrations to the Inner Ear.
- The Inner Ear, Which Contains the Cochlea and the Vestibular Nerve. Here, Sound Vibrations Are Converted Into Nerve Impulses for the Brain.
Rules for the Ears on Passport Photos
In the passport photo requirements, the ears are included under the section of "facial features."
Unlike the earlobes, which are addressed separately, the ears themselves do not need to be fully visible in the photo. However, the ear attachment must be visible, as it is used to determine the width of the face. If the sides of the face are fully covered, the ear attachment cannot be determined, and this is not acceptable for passport photos.
