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.
What else can I help you with?
Receives sounds and sends them through the auditory canal to the eardrum?
Sounds are received by the outer ear (pinna) and travel through the auditory canal to reach the eardrum (tympanic membrane). The vibrations of the eardrum then set the middle ear bones in motion, which transmit the sound to the inner ear for further processing.
What happens when sound waves reach your outer ear and how does it impact your hearing?
When sound waves reach your outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the tiny bones in the middle ear, which amplify the sound and send it to the inner ear. In the inner ear, the vibrations are converted into electrical signals that are sent to the brain for processing. This process allows you to hear and interpret sounds. If there are any issues with the outer ear, such as blockages or damage, it can affect the transmission of sound waves and impact your hearing ability.
What is the function of the auditory nerve in the ear?
The auditory nerve in the ear carries sound signals from the inner ear to the brain, allowing us to hear and process sounds.
What role does the inner ear play in the process of hearing sounds?
The inner ear plays a crucial role in the process of hearing sounds by converting sound vibrations into electrical signals that are sent to the brain for interpretation. This is done through the cochlea, a spiral-shaped structure in the inner ear that contains hair cells responsible for detecting sound waves and transmitting them to the brain via the auditory nerve.
What is the function of the middle ear in the auditory system?
The middle ear in the auditory system helps transmit sound vibrations from the outer ear to the inner ear. It also amplifies and adjusts the sound waves before they reach the inner ear, where they are converted into electrical signals for the brain to interpret as sound.
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
Receives sounds and sends them through the auditory canal to the eardrum?

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 happens when sound waves reach your outer ear and how does it impact your hearing?
When sound waves reach your outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the tiny bones in the middle ear, which amplify the sound and send it to the inner ear.

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 do you call the smallest muscle found in the inner ear?
The smallest muscle in the inner ear is called the stapedius muscle. It is located in the middle ear and is responsible for stabilizing the stapes bone, which is involved in the transmission of sound vibrations to the inner ear. The stapedius muscle helps to protect the inner ear from loud sounds by reducing the movement of the stapes.
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 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 is the function of the auditory nerve in the ear?
The auditory nerve in the ear carries sound signals from the inner ear to the brain, allowing us to hear and process sounds.
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.
