Function |
|
Outer ear |
Pinna and external auditory meatus (canal) |
The sound waves direct at pinna and reaches to tympanic Membrane (the eardrum) through the canal. |
|
Middle ear |
Three ossicles called the malleus, incus, and stapes. They are commonly referred to in English as the hammer, anvil, and stirrup. |
As the hammer is connected to the eardrum. When the hammer vibrates, it transmits the sound to the other two bones, i.e. to the anvil and stirrup. These sound waves are amplified up to 20 times of original waves |
|
Inner ear |
The cochlea, a coil-like structure |
The Cochlea, a coil-like structure, sends the sound to the brain as some amount of fluid (labyrinth) is present inside the cochlea These electrical impulses then go to the auditory nerve. This is exactly what we perceive as sound. It helps in maintaining body balance. |
