The Human Ear:

Structure of Human Ear

Our ears allow us to receive audible frequencies in our surroundings. They then convert these sounds into electrical signals which are then passed through a special nerve called the auditory nerve to our brain. The brain that interprets these signals and responds accordingly.

Pinna – The outer part of the ear that gathers sound from the environment.

Auditory Canal – Sound collected from the surroundings passes through the Auditory Canal.

Eardrum or Tympanic Membrane – It is located at the end of the auditory canal. The eardrum when receives a compression moves inwards because of increased pressure. Similarly, when it receives refraction it moves outwards due to a decrease in pressure. As a result, it starts to vibrate inwards and outwards on receiving a sound wave.

The Middle Ear – It consists of three bones (hammer, anvil and stirrup). These bones amplify the vibrations produced by the eardrum. These vibrations are then passed onto the inner ear by the middle ear.

Cochlea – It is located in the inner ear. It converts the vibrations into electrical signals which are then carried to the brain by the auditory nerve.
