How the ear works

How the ear works


Many of us take for granted a very
extraordinary organ… our ears To understand the ear, we need
to understand what sound is. The speakers you are
listening to right now are vibrating- flexing in and out causing a
wave of pressure through the air. The frequency of these waves,
or the speed at which the sound-creating surface moves back and forth
affects the pitch of the sound. The level of air pressure in each wave is
directly related to how loud the sound is. The outer part of our ear catches these waves. It faces forward and has a specially designed
structure of curves helping us to determine the direction of the sound, and emphasize
frequencies used in human speech Now that the sound waves are caught, they travel
through the ear canal and strike against our “eardrum,” a thin membrane about 10 mm wide. Now that we received the sound,
the middle ear transfers this energy. The smallest bones in your body, the Malleus,
Incus, and Stapes start in motion. The Malleus is attached to the eardrum,
and as the sound travels along the force is amplified by leverage
until it arrives at the Stapes, which acts like a reverse piston
creating waves in the fluid of the inner ear. The most significant increase in pressure is
caused by pneumatic amplification. The face of the stapes has a
surface area of 3.2 square mm, while the “eardrum” has a
surface area of 55 square mm. Using this, along with leverage through
the Malleus and Incus, the final pressure is 22 times greater than when
the sound first arrived. Now we come to the most complicated
part of hearing… the Cochlea. In reality, it is coiled up, but it is easier to
understand straightened out. There are actually three chambers inside,
but lets take a look at the central part. The Stapes is causing pressure waves
to travel through the structure. Along the inside wall is about
20-30k reed like fibers. As the waves move along
they encounter fibers with the correct resonant frequency
and energy is released. These fibers aren’t actually what give us the
signal that we heard something. There is a special structure next to these
fibers containing hair cells. When the hair fibers resonate, they cause the
hair cells to move, which then sends an electrical impulse to the
Cochlear nerve, and on to the brain. Certain pitches of sound will
resonate in specific locations, and louder sounds will cause
more hair cells to move. Our brain interprets all this raw data, making it possible to enjoy things like music,
or an engaging conversation. Just to think that all of this is happening in
your head right now at full speed. This is just one of the amazing systems
found in the human body that go far beyond our
humble human understanding.

  1. God made a precious thing on the human body because without human ear 👂 we can't hear anything those are most precious in our life an we got it

  2. Subhan Allah, The creator of entire universe who has given every such organs to sustain life, benefit and to enjoy..such an high infinite intelligence that we can't understand , The incomparable , The one

  3. قال الله تعالى:"وفي الارض آيات للموقنين ، وفي انفسكم افلا تبصرون " -الذاريات،الآية:21-20
    "And on the earth are signs for the certain [in faith] ،
    And in yourselves. Then will you not see? " -(51: 20،21)

  4. Goodness, half the comments I've seen are about how God or Allah created these/us. Like yo, this is a video teaching a simplified version of the hearing mechanism, not a preaching site. And what of Atheists or religions which do not have god(s)?

  5. Yes Animation make it possible to understand, but we humans don't care about beyond greatness senses of our own human body and want to study alien's. We really need a tuners for our brain 😂😂😂😂

  7. These animations help to understand the process, but I think this one is not totally correct. The movement of the ossicles should be in the same direction so that if the tympanic membrane swings out, the stapes should push in. If it worked like depicted all sound would be phase inverted. Maleus and Incus should not be able to move towards each other, because the amplification would not happen this way.

  8. Why everyone attribute all this to God?
    Who is God? Who create God? What's his/her entity?
    Where's this God come from?
    None are able to describe, because God himself/herself wasn't able to describe him/herself.
    According Qur'an sura alnoor, God states he is a shiny light, whom consume pure Olive oil, not from east nor west.
    So is this God?
    Monotheism God is just an image ,who creates by human brain and adds lots of definition and made him a universal God.
    E.g.. human race left Africa due to dwindling of meat supply, human start to eat human, weakest one was the vulnerable one. Human race in African region had blood type O, black skin, the weakest managed to escape to Europe and Asia, they start eating plant based food or dairy products. This change in dietary and geographical position leads mutation in genes and skin color. This doesn't occur over night but took thousands of years, here blood type A emerge , those who consume grains and legumes, eventually changed their blood chemistry, and blood type B those who rely on animal product such like dairy. Skin colour also based on needs of sun mutated, light skin colour produced due to cold weather and Olive skin based on geographical position and human body demands of sun.
    Science always against the stupid ideology of religions. Blood type B are people whom CHERISH spiritualism and invented all religions foundations. Majority of Jaws people carrying B blood , Indians majority are blood type B, Buddhism and so on are blood type B and creator of God and spiritualism.
    Don't Claim that God responsible for all these creation, human are formed from bacteria , and mutate based on geographical location. It's earth, climate, weather brings change and mutation on human and form human, NOT GOD.

  9. It's incredible every video like this has a bunch of religious nutjobs in the comments. A book written 2000 years ago buy a bunch of men who didn't know where the sun went at night will not have all the answers.

  10. THE AIR:
    A Window onto Divine Unity
    In His Name, be He glorified!
    And there is nothing but it glorifies Him with praise.
    My very dear and loyal brothers!
    My brothers, I observed in a subtle point concerning God's unity, which suddenly became clear while studying the page of the air on a journey of the imagination and mind, that is, in the word HE (HU) in the phrases THERE IS NO GOD BUT HE, and, SAY HE IS GOD, (and that was only in its material aspect) that the way of belief is infinitely easy, easy to the point of being necessary, and that the way of misguidance and associating partners with God is infinitely difficult, so difficult as to be impossible. I shall explain that long and extensive point with an extremely brief indication.
    Yes, if soil, one handful of which can act as a flower-pot for hundreds of plants in turn, is attributed to nature or causes, it becomes necessary either for there to be present in such a handful hundreds of immaterial machines, indeed, machines and factories to the number of the plants, or for each particle of that small amount of soil to know how to make all those different plants together with their different characteristics and living organs; quite simply, each would have to possess infinite knowledge and limitless power like a god.
    The same is true for the air, which is a place of maximum manifestation of the Divine will and command; either there would have to be present on a minute scale in each of its molecules, in each waft of wind, each breath, and in the tiny amount air expended with the word HE, the innumerable different exchanges, centres, receivers and transmitters of all the telephones, telegraphs and radios in the world so that each could perform those innumerable acts at the same time; or else, each particle of each molecule of air exhaled with HE, and indeed of the element air, would have to possess abilities and personalities to the number of all the different telephone users, telegraphers, and those who speak on the radio, and know all their different languages, and broadcast them to the other particles at the same time. For such a situation is actually apparent, and every bit of air possesses that ability. Thus, in the ways of the unbelievers, Naturalists, and Materialists not one impossibility, but impossibilities and difficulties are clearly apparent to the number of molecules of air.
    If attributed to the All-Glorious Maker, however, the air together with all its particles becomes a soldier under His command. With its Creator's permission and through His power, and through being connected to its Creator and relying on Him, and through the manifestation of its Maker's Power, in an instant with the speed of lightning, and with the ease of uttering the word HE and the movement of the air in waves, its innumerable universal duties are performed as easily as an orderly, single duty of a single particle. That is to say, the air becomes a page for the endless, wonderful, and orderly writings of the pen of power, and its particles become the nibs of the pen, and their duties the points inscribed by it. The air functions as easily as the movement of a single particle.
    Thus, while on my journey of contemplation prompted by the phrases THERE IS NO GOD BUT HE, and, SAY, HE IS GOD, and while observing the world of the air and studying the page of that element, I witnessed this brief truth with utter certainty and clarity, and in detail. And I understood with 'knowledge of certainty' that it was because there is in the word HE, in the air of its utterance, such a brilliant proof and flash of Divine unity, and also in its meaning and allusions such a luminous manifestation of Divine oneness and powerful proof of Divine unity, and in that proof an indication that since the pronoun HE is unconditional and indefinite, it suggests the question, "Who does it refer to?" that both the Qur'an of Miraculous Exposition and those who constantly recite the Divine Names frequently repeat this sacred word in the station of unity.
    If, for example, there is one point on a piece of white paper and two or three other points are jumbled around with it and then someone who already has numerous jobs tries to distinguish them, he will be confused; and if many burdens are loaded on a small creature, it will be crushed; and if numerous words issue from one tongue and enter one ear altogether at the same time, their order will be broken and they will be a muddle.
    Despite this being the case, I saw with complete certainty that with the key and compass of HE, although thousands of different points, letters and words had been put in each molecule and even in each particle of the element air, through which I journeyed in my mind, neither did they become mixed up nor did they spoil their order; and although they performed a great many different duties, these were carried out without being confused in any way; and although very heavy loads were laid on each molecule and particle, they bore them in order without lagging or displaying any weakness at all. And I saw that thousands of different words of all different sorts enter and issue with perfect order from what is in effect those minute ears and tongues without being mixed up and spoilt in any way, they enter those minute ears and issue from those tiny tongues, and by performing these extraordinary duties, each particle and each molecule declares through the enraptured tongue of its being and its perfect freedom, and through the testimony and tongue of the above truth: THERE IS NO GOD BUT HE, and: SAY, HE IS GOD, THE ONE, and travels among air-clashing waves like storms and lightning and thunder without in any way spoiling their order or confusing their duties. One duty is not an obstacle to another duty. I observed this and was utterly certain.
    That is to say, either every particle and piece of the air has to possess infinite wisdom, knowledge, will, and power, and the qualities for being absolutely dominant over all the other particles so that it can be the means of those functions being carried out, which is absurd and impossible to the number of particles, and no devil even could imagine it, or else, and it is self-evident to the degree of 'knowledge of certainty,' 'vision of certainty,' and 'absolute certainty' that the page of the air functions through the boundless, infinite knowledge and wisdom of the All-Glorious One, and is the changing page for the pen of Divine Power and Determining, and like a signboard for writing and erasing, known as a Tablet of Appearance and Dissolution, which has the function of the Preserved Tablet in the world of transformation and change.
    Thus, just as the element of air demonstrates the above-mentioned wonders and manifestation of Divine unity in only the duty of transmitting sound and shows the impossibilities of misguidance, so does it perform other important duties with order and without confusing them, such as transmitting subtle forces and energy, like electricity, light, and the forces of attraction and repulsion. At the same time as conveying these, with perfect order, it carries out duties essential for the lives of plants and animals, such as respiration and pollination. It proves in decisive fashion that it is a place of maximum manifestation of the Divine will and command. I came to the firm conclusion that it proves that in no way is there any possibility of vagrant chance, blind force, deaf nature, confused and aimless causes, and powerless, lifeless, unknowing matter interfering in the writing and duties of the page of the air. And I understood that every particle and part of it says with the tongue of its being: SAY, HE IS GOD, THE ONE, and: THERE IS NO GOD BUT HE. Just as with the key of HE I saw these wonders in the material aspect of the air, so also, as a HE, did the element of air become a key to the World of Similitudes and the World of Meaning.
    I saw that the World of Similitudes is all the time taking innumerable photographs without confusing them, and that each photograph contains innumerable events occurring in this world. I understood that it was a gigantic camera, and a vast cinema of the hereafter thousands of times larger than the world for showing the fruits of the transitory and impermanent states and lives of ephemeral beings in eternal theatres, for showing to those enjoying everlasting bliss in Paradise scenes from their old memories and adventures in this world. {[*]:Since the time and place and conditions do not allow this to be proven with firm proofs and arguments like clear facts, it is cut short here.}
    While the faculties of memory and imagination, which are two proofs, two small examples, and two points of both the Preserved Tablet and the World of Similitudes situated in man's head, are as tiny as lentils, within them are written in perfect order and without being mixed up as much information as may be contained in a large library. This proves decisively that large examples of those faculties are the World of Similitudes and the Preserved Tablet.
    It is definite and certain with 'knowledge of certainty' that the elements of air and water, and the element air and water like seminal fluid in particular, are far superior to the element of earth, and are written with more wisdom and will, and with the pen of Divine Determining and Power, and that it is completely impossible for chance, blind force, deaf nature, and lifeless and aimless causes to interfere in them, and that they are a page of the pen of Power and the wisdom of the All-Wise One of Glory.
