The following article is written to provide a general understanding of the structures within the auditory system and how they function. The auditory system is comprised of three components; the outer, middle, and inner ear, all of which work together to transfer sounds from the environment to the brain.

The ear is the organ of both hearing and equilibrium. Hearing is the transduction of sound waves into a neural signal that relies on the structures of the ear. The outwardly visible structure that is often referred to as the ear is more correctly referred to as the outer ear external ear , or the auricle.

Human ear , organ of hearing and equilibrium that detects and analyzes sound by transduction or the conversion of sound waves into electrochemical impulses and maintains the sense of balance equilibrium. The human ear, like that of other mammals , contains sense organs that serve two quite different functions: that of hearing and that of postural equilibrium and coordination of head and eye movements. Anatomically, the ear has three distinguishable parts: the outer, middle, and inner ear. The outer ear consists of the visible portion called the auricle , or pinna, which projects from the side of the head, and the short external auditory canal , the inner end of which is closed by the tympanic membrane , commonly called the eardrum. The function of the outer ear is to collect sound waves and guide them to the tympanic membrane. The middle ear is a narrow air-filled cavity in the temporal bone.

Hearing is the process by which the ear transforms sound vibrations in the external environment into nerve impulses that are conveyed to the brain , where they are interpreted as sounds. Sounds are produced when vibrating objects, such as the plucked string of a guitar , produce pressure pulses of vibrating air molecules , better known as sound waves. The ear can distinguish different subjective aspects of a sound, such as its loudness and pitch , by detecting and analyzing different physical characteristics of the waves. Pitch is the perception of the frequency of sound waves—i. Frequency is usually measured in cycles per second, or hertz.

Your Inner Ear Explained

The ear is the sense organ that enables us to hear. Hearing can be defined as the perception of sound energy via the brain and central nervous system. Hearing consists of two components: identification of sounds what the sound is and localisation of those sounds where the sounds are coming from. The ear is divided into three main parts — the outer ear , the middle ear , and the inner ear. The inner ear is filled with fluid.

Ear anatomy

Your inner ear is the deepest part of your ear. The inner ear has two special jobs. It changes sound waves to electrical signals nerve impulses. This allows the brain to hear and understand sounds.

The inner ear internal ear , auris interna is the innermost part of the vertebrate ear. In vertebrates, the inner ear is mainly responsible for sound detection and balance. The inner ear is found in all vertebrates, with substantial variations in form and function.

NCBI Bookshelf. The human ear is the organ of hearing and equilibrium. It detects and analyzes sound by the mechanism of transduction, which is the process of converting sound waves into electrochemical impulses.

В обычных условиях такое действие считалось бы недопустимым. Но в сложившейся ситуации никакой опасности в загрузке в ТРАНСТЕКСТ этой программы не было, потому что коммандер точно знал, что это за файл и откуда он появился. - Несмотря на все мое уважение к вам, сэр, - продолжал настаивать Чатрукьян, - мне никогда еще не доводилось слышать о диагностике, в которой использовалась бы мутация… - Коммандер, - перебила его Сьюзан, которая не могла больше ждать.  - Мне действительно нужно… На этот раз ее слова прервал резкий звонок мобильного телефона Стратмора.

 Я не хочу никоим образом нарушать покой директора и говорить с ним о кризисе, в то время как он не в состоянии предпринять хоть что-нибудь. Сьюзан понимала, что коммандер прав. Даже в такие моменты ему удавалось сохранять ясность рассудка. - А вы не думали о том, чтобы позвонить президенту.


Hearing starts with the outer ear. When a sound is made outside the outer ear, the sound waves, or vibrations, travel down the external auditory canal and strike​.


Но я хочу иметь копию. Я хочу открыть этот проклятый файл и ознакомиться с созданной Танкадо программой. Сьюзан была столь же любопытна, как и ее шеф, но чутье подсказывало ей, что расшифровка алгоритма Цифровой крепости неразумна, какой бы интерес это ни представляло.

 Ключ находится в Испании, - еле слышно произнесла Сьюзан, и все повернулись к. Это были ее первые слова за очень долгое время. Сьюзан подняла голову.

Этот враждебный мир заполняли рабочие мостки, фреоновые трубки и пропасть глубиной 136 футов, на дне которой располагались генераторы питания ТРАНСТЕКСТА… Чатрукьяну страшно не хотелось погружаться в этот мир, да и вставать на пути Стратмора было далеко не безопасно, но долг есть долг. Завтра они скажут мне спасибо, - подумал он, так и не решив, правильно ли поступает. Набрав полные легкие воздуха, Чатрукьян открыл металлический шкафчик старшего сотрудника лаборатории систем безопасности. На полке с компьютерными деталями, спрятанными за накопителем носителей информации, лежала кружка выпускника Стэнфордского университета и тестер. Не коснувшись краев, он вытащил из нее ключ Медеко.

The ears are paired organs, one on each side of the head with the sense organ itself, which is technically known as the cochlea, deeply buried within the temporal.

The organ of Corti is a specialized structure of cells that forms the sensory organ of hearing. It is situated within the scala media on the basilar membrane (Figure 2​.
