How do we hear?
Hearing is unusual kind of feeling. Your ear is Static piece of equipment on human body. your outer ear catch sound wave and direct them into a complex sensor. As soon as sound wave trouble through ear canal, they make your eardrum and tiny bones vibrate. Nerves in human inner ear pick up on this vibration and turn them into electrical impulse to human brain. Your brain can then identify these sounds such as Speech, music, noise and more.Any problem related to hearing or you need suggestion you can contact our help line number 999 999 9999 or visit hearing solutions.
Structure of Ear:
Our ear mainly divided in to three parts
- Outer Ear
- Middle Ear
- Inner Ear
If any of sensory part is damaged then your entire sense of hearing is affected. This is because a part of your ear becomes blocked. Nerves may get damaged sound wave may not be processed properly. Once the vibrations cause the fluid within the tube to ripple, a wave forms on the tissue layer. Hairs cells—sensory cells sitting on prime of the basilary membrane—ride the wave. Hair cells close to the wide finish of the snail-shaped tube notice higher-pitched sounds, like associate baby crying. Those nearer to the middle notice lower-pitched sounds, like an outsized dog barking.
As the hair cells move up and down, microscopic hair-like projections (known as stereo cilia) that perch on prime of the hair cells bump against associate superimposed structure and bend. Bending causes pore-like channels, that area unit at the ideas of the stereo cilia, to open up. Once that happens, chemicals rush into the cells, making associate electrical signal.
The nervus vestibulocochlearis carries this electrical signal to the brain that turns it into a sound that we have a tendency to acknowledge and perceive.
If any of sensory part is damaged then your entire sense of hearing is affected. This is because a part of your ear becomes blocked. Nerves may get damaged sound wave may not be processed properly.
Hearing functionality in brief
Hearing process done through various step that change sound wave into electrical signal. our auditory nerve carries these signal to brain.
- Sound waves enter the outer ear after that pass-through a narrow gateway which is called the ear canal, which leads to the eardrum.
- The eardrum vibrates from the incoming sound waves and sends these vibrations into three tiny bones in middle ear. These bones are called as malleus, incus and stapes.
- The bones in the middle ear amplify, increase sound of vibration and send them into cochlea, snail shaped structure filled with fluid in the inner ear part. An elastic partition run from starting to the end of cochlea, dividedin to upper and lower part. This partition is called the basilar membrane because of it serve as the base/ground floor, on that key hearing sit.
- When the vibrations cause the fluidinside the cochlea to ripple wave form along the basilar
- Hair cell near the huge end of snail-shaped cochlea detect higher-pitched Sound who are closer to the centerdetect lower pitch sound Example of this one dog barking.
The auricular nerve carries this type of electrical signal to the brain which are converted into a sound that we remember and understand.
