The three bones of the middle ear, commonly referred to as the hammer, anvil, and stirrup (technical: Malleus, Incus, and Stapes) transmit the sound through a part of the ear known as the oval window. The membrane around the oval window constitutes the boundary between the middle and inner ear. The sound (which is literally a wave, or vibration) then travels into the cochlea, which is the snail shell-like region of the inner ear. Due to the varying diameter of this structure (it is essentially a rolled up cone), the sound travels until it locates its fundamental frequency.
The fundamental frequency is the point at which the original sound waves and the sound waves bouncing from the cochlea's surface are at the precise distance apart that complete constructive interference occurs. basically, the two waves line up one cycle apart, making the sound louder. (Destructive Interference is when the two cancel or nearly cancel each other out.) The best way to explain this phenomenon is at a concert or Baseball game: If you are at one point, you can hardly hear the speaker or the sounds overlap, while in another very nearby location the sounds overlap and get louder. Try it next time you're at an event with big speakers.
Back to the ear. The point at which this interference occurs moves the hairs inside the cochlea. Tiny mechanoreceptors (receptors that feel motion) receive this signal, find the general point all around the circumference of the cochlea that the sound is causing the hairs to move, and then transmits the signal down the auditory nerve to the brain. Know one is exactly sure of how this part works, as nerve signals are still largely not understood. More research can be completed on this part of the process, however.

∙ 12y agoIt travels through the outer ear canal, vibrates the ear drum in the outer ear. Then, in the middle ear it transfers the sound waves through the auditory ossicles. They transmit the sound vibrations to the oval window which then transmits the sound waves to the endolymph fluid inside the cochlea. The Organ of Corti then sends the stimulation via the cochlear nerve to the brain where it is interpreted as sound.

∙ 10y agoInner ear ossicles are attached to the oval window of the inner ear. With vibration of ossicles the oval window also vibrates. So the fluid inside the inner ear also vibrates. These vibrations are permitted by round window. There are hair cells of different lengths. They resonates with the frequency of ossicles. The nerve cells below gets stimulated and transmits the resultant frequency of many sound waves. So cells of different frequency gets transmitted and the brain can differentiate the hundreds of different sounds at a time. Two ears give the stereoscopic effect.

How does the message from sound waves get to your brain?
Sound waves enter the ear, go through the ear canal to the ear drum, through the middle ear to the inner ear where the sound wave (vibrations) reach a mechanism called a cochlea which converts the vibrations to electrical impulses. The electrical information is guided via nerve cells to the brain which interprets the electrical information as sounds.
Does The oval window separate the middle ear from the inner ear?
The oval window is part of the middle ear but in theory, yes it does separate the middle ear from the inner ear.
What parts of the ear are responsible for hearing?
there are 3 part's... the outer ear, the inner ear, and the middle ear. all of these are responsible for hearing but the inner is for balance also.
In your ear a part that looks like a coiled tube is the?
cochlea
What are the structures of equiloibrium?
The ears help with balance. The structures of the ear that help with keeping an equilibrium is the inner ear. The inner ear is responsible for hearing and balance.
Why do lower frequency sounds reach the end of the inner ear which is called the apex and higher frequencies don't?
they have longer wavelength
How does your ear respond to different sounds?
The ear responds logarithmically to different sounds. The ear which is divided into inner ear, outer ear and middle ear responds differently according to sound frequency and intensity.
What does the ear canal do?
The ear canal directs sounds from the external ear, which is designed to capture sounds, to the more sensitive eardrum and inner ear (which are within the skull and better protectedWax in the ear canal keeps dust and small animals away from the eardrum. In cats and other animals, the ears must sometimes be cleaned of mites.The ear canal directs sounds from the external ear, which is designed to capture sounds, to the more sensitive eardrum and inner ear (which are somewhat better protected).The ear canal directs sounds from the external ear, which is designed to capture sounds, to the more sensitive eardrum and inner ear (which are somewhat better protected).It channels sound to the ear drum
What are the functions of the three main parts of the human ear?
The three main parts of the ear are the outer ear, middle ear and the inner ear. The outer ear's function is to funnel or pass sound waves through the ear to the middle ear. The middle ear's function is to protect the inner ear from damaging sounds. In the inner ear, sound waves are converted into nerve impulses which are transmitted to the brain to be interpreted. The inner ear also serves as the main organ of balance for the body.

What part of the inner ear do the receptors convert sounds vibrations into nerve impulses?
Cochlea
What three kinds of body parts do sound waves travel through before they reach the brain?
Outer ear, middle ear and inner ear
What is the true organ of hearing?
The sound waves enter the ear until they reach the Auditory ossicles (The middle ear) then moves into the inner ear as it vibrates the ossicles then contrast the muscles and flattens the hair of the inner ear to make a person hear.
What would be the effect on the loudness of sounds if you held the mouthpiece of a megaphone to your ear?
Sounds would reach your ear, but sound all distorted. Like holding a seashell to your ear. So not much effect.
What occurs when sound waves don't pass through the outer to the inner ear?
You don't hear anything. They don't actually have to get there through the outer ear. If your ear is plugged, or if your 'tympanum' (ear drum) is broken, the vibrations can conduct through the bone that you feel behind your ear. But they do have to get to the inner ear somehow. If vibrations don't reach the cochlea in the inner ear, then you don't hear anything.
Pain in your neck with ear turning red and feels hot what can this be?
It sounds like an inner ear infection. Best go see a doctor.
What is the stirrup doing in the human ear?
It's a part of the "transducer" that converts air sounds (large, low pressure) into liquid sounds (low amplitude, high pressure) - it connects the ear drum to the inner ear (a thin section of the skull.
