How We hear
Our ears are among the body’s most complex organs. They receive and transmit sound waves to the brain where they are analyzed and interpreted.p
But how does our hearing actually work?
Take a tour of the ear
Each stage is described below the video.
Stage 1 – The outer ear
Stage 2 – The middle ear
These bones are commonly referred to as the hammer, anvil, and stirrup and they connect the eardrum to a membrane between the middle and inner ear, known as the “oval window”.
The movement of the oval window transmits the pressure waves of sound in to the inner ear.
Stage 3 – The inner ear
The passageways of the cochlea are lined with about 20,000 microscopic hair cells that convert sound vibrations into nerve impulses. These impulses are then sent to the brain which interprets the impulses as meaningful sounds.
