OUR EARS AND HOW WE HEAR Hearing depends on a series of events that change sound waves in the air into electrical signals. Your auditory nerve then carries these signals to your brain through a complex series of steps. 1. Sound waves enter your external ear and go through a thin path called the ear trench, which prompt your eardrum. 2. Your eardrum vibrates from the approaching sound waves and sends these vibrations to three small bones in your centre ear. These bones are known as the malleus, incus, and stapes. 3. The bones in your centre ear intensify, or build the sound vibrations and send them to the cochlea, a snail-moulded structure loaded with liquid, in the internal ear. A versatile layer runs from the earliest starting point to the end of the cochlea, part it into an upper part and a lower part. 1

OUR EARS AND HOW WE HEAR
Hearing depends on a series of events that change sound waves in the air into electrical signals. Your auditory nerve then carries these signals to your brain through a complex series of steps.
1. Sound waves enter your external ear and go through a thin path called the ear trench, which prompt your eardrum.
2. Your eardrum vibrates from the approaching sound waves and sends these vibrations to three small
bones in your centre ear. These bones are known as the malleus, incus, and stapes.
3. The bones in your centre ear intensify, or build the sound vibrations and send them to the cochlea, a snail-moulded structure loaded with liquid, in the internal ear. A versatile layer runs from the earliest starting point to the end of the cochlea, part it into an upper part and a lower part.

4. The sound vibrations cause the liquid inside your cochlea to swell, and a voyaging wave structures
along the film. Hair cells — tactile cells sitting on top of the layer —"ride the wave”.
5. As the hair cells climb and down, their bristly structures knock up against an overlying layer and tilt to
the other side. This tilting activity reasons pore-like channels on the surface of the swarms to open up.
At the point when that happens, certain chemicals surge in, making an electrical sign.
6. Your sound-related nerve conveys this electrical sign to your mind, which makes an interpretation of it
into a sound that you perceive and get it.
Hair cells close to the wide end of the snail-moulded cochlea recognize higher-pitched sounds, for
example, a phone ringing. Those closer to the inside identify lower-pitched sounds, for example, a
substantial pooch yapping.
