Why do I still hear myself when I cover my ears with my hands?

First of all, sound is a kind of mechanical vibration, and the sound that you hear by covering your ears is the vibration of the vocal cords that is transmitted through the bones to the ossicles.

to the vibration of the cochlea. Others hear your voice through the air through the vibration bones, air is the transmission medium, different media conduct, the vibration heard is also different, such as what is heard in diving. All you need is airborne sound.

Yes, while you speak, you hear sounds that are actually airborne + bone conduction. Bone conduction is faster than air, but because the distance is negligible, the sound heard by the nerve response is a conjunction of the two mediators.

After you cover your ears, it is equivalent to disconnecting the air transmission, and what you can hear is a mixture of talking sound + blood + vibration of the inner cavity, etc., which will sound muffled.

Others can only hear the airborne sound, which is the closest sound you get through the recording.

Strictly speaking, what you hear and what others hear is your real voice, but different transmission routes bring different sound quality and timbre, and you just want to know what your voice is like in other people's ears.

To add an example: people, who can hear each other's voices through helmet contact in a cosmic vacuum.

The sound passes through the skull, jaw.

It can also be transmitted to the auditory nerve and cause hearing In science, this conduction of sound is called bone conduction Some people who have lost their sense of hearing can use bone conduction to listen to sounds, maybe for example, you will understand: cover your ears with your hands, talk to yourself, no matter how small the sound, we can hear what we are saying, this is the result of bone conduction.

The outside sound heard by the human ear is the vibration of the outside air passing through the eardrum.

The transmission of sound information to the auditory nerve, coupled with the processing of the brain, forms what we call hearing. The sound we hear when we speak by ourselves is transmitted directly from the inside to the auditory nerve by the skull, and the brain processes it to form another kind of hearing. That is to say, the former allows others to hear the sound by means of airborne transmission; The latter travels through the skull, allowing itself to hear sounds.

This is because it is audible in itself, and your ears are not covered.

Excuse me, are you covering your ears and stealing the bell, your ears are also a medium, and they will also transmit sound.

This is because the sound waves inside us also travel, so they are heard.

The sound you hear when you cover your ears is the vibration of the vocal cords that passes through the bones and travels from the ossicles to the cochlea.

This should be said to be a cover-up. The propagation of sound cannot be blocked by the hand.

This is because of the propagation of sound in the body, of course, you can hear it.

Because when you cover your ears with your hands, you can hear a much narrower range.

Isn't this just covering your ears and stealing the bell, of course you can hear it, because there is no stifling the source.

Because the sound of covering your ears and speaking may use some of the principles of bone conduction, it will sound more muffled and louder, and when you speak with your ears open, the sound is transmitted through the air. So it's not the same as what you hear when you open your ears and speak.

Because when you cover your ears and speak, you block out other outside sounds, so that you can hear more clearly, even if you are very quiet, you can hear what you are saying.

The external sound wave information is transmitted from the external auditory canal to the eardrum, causing the eardrum to vibrate, and is transmitted to the cochlea of the inner ear through the three ossicles, and the auditory receptors in the cochlea receive the information, and along the nerves related to hearing, the information is transmitted to the auditory center of the cerebral cortex to form hearing, and people hear sounds.

Sound is an elastic medium that transmits energy in the form of vibrations, which manifests itself as a change in density and pressure. The propagation change or displacement involves a vibrating object (i.e., the vibration source), and the elastic medium can be a gas, a solid, or a liquid. Sound cannot travel in a vacuum.

In our area of expertise, a mention and beam to elastic media almost always refers to air. Any medium is made up of molecules. When a medium is at rest, a vibrating object causes these molecules to move back and forth repeatedly at the same speed as the vibrating body, producing sound.

Since the molecules in the air are invisible to the naked eye, let's imagine an example of 10 people (molecules) lined up side by side, each with a distance of 10 cm (at rest). You, as the vibrator (equivalent to the source of vibration), push the shoulder (molecule) of the first person in the direction of the line, and a chain reaction occurs, where everyone hits the next person (molecule) and then bounces back.

In the process, some people are pushed together, while others are disturbed and slowly separated until they return to their normal stationary position. "You" have created a wave of vibrational motion and have been able to propagate, but only "pressure" or "energy" has been transmitted, and "people" have not been propagated.

Because when you cover your ears with your hands, the sound is completely dependent on bone conduction, so you will feel very loud, but in fact, others will hear the same sound as if you did not cover your ears

The sound we hear ourselves is heard by visceral resonance, which means that the sound you hear is the sound of the organs in your body vibrating after you speak, and then transmitted to the auditory nerve. So it's not the same way you hear your own voice as others hear you.

In addition, because the wavelength of the sound we emit is different from the wavelength of the machine such as ** or the computer, in this way, because the way the two sounds are conveyed does not match, it will also cause your voice to be different in reality and ** or recorded.
