Before understanding what can lead to hearing issues, it is practical to understand how the ear functions. The outer ear, middle ear, and inner ear are the three primary components of the ear. From the skin fold on the outside of the skull to the eardrum, there is the external ear. Sound waves are funnelled fast to the eardrum via the outer ear.
The middle ear starts at the eardrum. The middle ear space, which is usually air-filled, is located behind the eardrum. The middle ear area contains the Eustachian tube entrance. The apex of the throat and the middle ear area are connected by this tube. The tube frequently opens and closes during the day. It might open when we swallow or yawn, for instance. It occasionally makes noises when it opens or "uncovers". When it opens, it lets outside air into the middle ear, bringing in fresh air. This tube aids in bringing the air pressure in the middle ear to its external counterpart. That is why when we change altitude, like when crossing a mountain or taking off and landing in an aeroplane, our ears explode.
The malleus, the anvil, and the stirrup are the names of the three small bones that make up the middle ear. These bones link together to make a chain. The malleus, the first bone, is joined to the eardrum. The oval window, a further small membrane, is joined to the stirrup, the last bone. Cortexi
The cochlea, or inner ear, starts at the oval window. The last of the small bones pushes up against the oval glass as the sound enters the ear. More than 15,000 small nerve terminals known as hair cells can be found inside the cochlea. There is fluid surrounding these hair cells. Sound waves are transformed into electrical impulses by hair cells and sent to the brain via the auditory (hearing) nerve. The sounds become something significant to you after the brain processes these impulses.https://www.outlookindia.com/outlook-spotlight/cortexi-reviews-legit-users-shocking-feedbacks--news-273963
