Ears – Hearing or Audioception

• Ears are the auditory sense organs of our body.
• They help us to perceive sounds.
• Our auditory system detects vibrations in the air and this is how we hear sounds. This is
known as hearing or audioception.
• The ears are divided into 3 sections, namely, outer ear, inner ear, and the middle ear.
• All sounds are basically vibrations, so the outer ear transfers these vibrations into the ear
canal, where these vibrations are transformed by the brain into meaningful sound.
• Apart from hearing, this sense is also important for balancing our body or equilibrium.

Taking Care of ears

a) Do not clean an ear with a sharp pointed object, it may damage the ear.
b) Don’t allow water to remain in the ears after a bath or after swimming, clean ears with dry
towel.
c) Don’t listen to loud music for long periods of time.
d) Don’t use headphones continuously for long hours.
