Why does bone conduction propagate faster than air conduction in the afferent pathway of sound?

Hello! In terms of conduction pathways, air conduction propagation: sound waves--- auricle--- external auditory canal--- tympanic membrane--- malleus--- incus--- stapes--- vestibular window--- external and endolymphtic fluid--- spiral organs--- auditory nerve--- auditory center; Bone conduction propagation:

The skull vibration ------ external and endolymphtic fluid--- spiral apparatus --- auditory ---nerve auditory center, and bone conduction is much less than air conduction through the transmission of the passer. In addition, in terms of the difference between the medium, the speed of sound propagation through the medium is solid, liquid, and gas, while bone conduction is transmitted through skull vibration, and air conduction is transmitted through the air vibration in the external auditory canal, so bone conduction will be faster. Hope mine can help you!

Air conduction propagation: sound waves --- auricles--- external auditory canal--- tympanic membrane--- malleus--- incus--- stapes--- vestibular window--- external and endolymphatic fluid--- spiral organs--- auditory nerve--- auditory center anvils.

Bone conduction propagation: sound waves--- cranial vibrations--- external and endolymphatic fluid--- spiral apparatus--- auditory nerve--- auditory center.

The transmission route of air conduction passes through more organs than bone conduction, so the speed of bone conduction is faster than that of air conduction.

There are two ways in which sound enters the inner ear: one through the external auditory canal.

tympanic membrane The pathway of the ossicular chain, called air conduction; Another way is to enter the inner ear directly through the vibrational conduction of the skull, which is called bone conduction. Physiologically, bone conduction is far less effective than air conduction, but it plays an important role when the pressurization effect of the middle ear is disrupted. This is also the option for bone-anchored hearing aids for some patients with atresia of the external auditory canal.

The basic acoustic principles. When sound waves are conducted from the skull to the cochlea.

, the vibration of the skull causes the lymphatic fluid of the inner ear to vibrate accordingly, which further causes the vibration of the basement membrane, resulting in hair cell excitation.

Figuratively speaking, air conduction is a way of air transmission to allow others to hear sound; Bone conduction, on the other hand, travels through the skull to allow oneself to hear sounds. Hope mine is helpful to you!

Hello: Why does bone conduction propagate faster than air conduction in the afferent pathway of sound?

There are two mechanisms by which sound is transmitted to the human ear: air conduction and bone conduction. Air conduction is conducted through air, and bone conduction is transmitted to the inner ear by vibrating the skull. Bone conduction propagation is faster than air conduction propagation, mainly because the propagation of air conduction passes through more human organs than bone conduction, I hope mine can help you!

Because the air-conduction headphones rely on the earphone diaphragm to drive the air in the ear canal, so as to encourage the eardrum to hear the sound, while the bone conduction headphones are to stimulate the ossicles to hear the sound by vibrating the "mastoid" bone behind the human ear.

There are two main ways of sound conduction:

1. In normal people, sound waves mainly pass through the outer ear, tympanic membrane and ossicular chain, and then enter the inner ear through the oval window to cause hearing, which is called air conduction.

2 Sound waves can also act directly on the skull, causing endolymphtic vibration to produce hearing, which is called bone conduction.

Bone conduction is much less effective than air conduction. When air conduction is impaired, the effect of air conduction is weakened or disappears, and the bone conduction effect is increased accordingly. Hearing loss or loss due to airconduction disorders such as eardrum or middle ear lesions is called transmitted hearing loss.

The loss or loss of hearing caused by a lesion such as the cochlea is called sensory hearing loss.

There are two ways for the human ear to perceive sound: air conduction and bone conduction, which are correct.

The sound is collected through the external auricle to the external auditory canal, causing the tympanic membrane to vibrate, and then driving the malleus to move to the incus and stapes, and the stapes floor vibrates and transmits energy to the perilymph of the inner ear through the vestibular window, and the perilymph flows like water in a bottle, driving the basement membrane fluctuations in it.

It is mainly done by the cochlea of the inner ear. When the sound of air conduction and bone conduction vibrates the perilymph, it also fluctuates the basement membrane that grows within it. The basement membrane is like a large row of toothbrushes arranged side by side from long to short.

That's right, when you speak, your vocal cords vibrate, produce sound, and then use the skull as a medium to transmit to your ears, and it can also use air as a medium to transmit to your ears, so there are two ways for people to perceive sound.

There are two ways in which sound is conducted. It is divided into air conduction and bone conduction.

Air conduction: sound waves--external auditory canal--tympanic membrane vibration--three ossicles--ovale--auricular fossa. (main conduction pathway).

Bone conduction: sound waves – cranial vibration – vibration of lymph within the cochlea. (Normally, this approach has little effect).

Sound waves—external auditory canal—tympanic membrane—malleus—stapes—vestibular window—perilymph of the vestibular step—endolymph of the spiral canal—spiral apparatus—spiral nerve—auditory center of the cerebral cortex.

"How Sound Travels".

(I guess what you're trying to ask may have something to do with "listening to your own voice differently than others listening to you"?) ）

The speed at which sound waves propagate in different media varies greatly, and the acoustic characteristics of sound waves such as amplitude, energy attenuation, etc., also differ.

For example, sound waves travel fast in solids and decay slowly (the opposite is true when they travel through the air), so even if sound comes from the same sound source, it sounds different when it travels through a solid and when it travels through the air.

The sound that a person hears when he speaks is a mixture of sound waves that are transmitted directly to the auditory nerve through solids such as jaws and muscles, and sound waves that are heard through the air to the eardrum.

When others listen to you, all they hear is the sound that travels from the air to their eardrums. So it sounds different.

Therefore, it will be very unaccustomed to listening to your own recordings, because you usually can't hear your own voice only from the air. ）

Because timbre is not only related to the structure, material and mode of sound emitting body, but also related to the sound transmission medium.

Bone conduction is different from the medium through which air conducts, so the sound effect is different.

The material and structure are different, the sound is propagated in the form of waves, and the timbre of the sound propagated by different media is different.

Mainly because solid sound transmission is much better than gas sound transmission, which is what the teacher taught me.

Bone and qi are the same.

The above answer is wrong! When the same object vibrates at the same frequency in the same situation our physics teacher said: you will hear it when you hit the table and make a sound (not sticking to the table), and if you stick to the table you will notice that the sound becomes louder This is because:

We know that in gas, solid, and liquid, the sound travels the fastest in the solid, and the slowest in the gas, because of the amount of energy consumed in the process of sound propagation, which consumes a lot in the air, so you find that the sound is very small; In solids, the energy consumption is small, so you find that the sound is very loud, which is a matter of the amount of energy consumed by the sound during the propagation, not the vibration frequency!

The reason may not be right, but it is definitely a problem of energy consumption) For example: if we throw a small ball in the air, we can throw it at a certain distance, if it is in water, we use the same mass and force to throw, and the distance will be very small, which is the problem of energy loss in the propagation process!
