Why is listening to your own voice different from recording?

This is a normal phenomenon, the recorded sound has machine error, and listening to your own voice and others listening to your own voice is not the same, others listen to your voice is transmitted through the air, and you listen to your own voice is mainly transmitted through the head bones, when you really listen to your own voice through the air, plus the machine error will sound very different, not a disease do not worry.

On the one hand, what we normally hear about ourselves is not really a sound, because the sound comes from our larynx and our ears are very close together, so what we hear is not what others hear. The sound of the recording is the sound that has been processed by the software, and even the fidelity is not its own pure sound.

The sound you hear when you speak on your own is not transmitted entirely through the air, but rather after your voice is pronounced, part of the sound is transmitted through your body to your ears.

Some of the sound is conducted through the air, and what you hear is a mixture of the two sounds; But when you're recording, it's completely air-transmitting sound waves, so it's completely different from what you're hearing.

This is related to acoustics, and ordinary microphones can't fully capture all the frequencies we speak! So the general microphone, the recorded sound is distorted, have you ever heard of a condenser microphone? The record company is a capacitor microphone!

A good one costs tens of thousands of yuan, as for the effect, you can experience it by buying a genuine CD!

There are different routes of transmission, one is bone transmission and the other is airborne transmission.

Yes. Because of the phenomenon of bone transmission, the voice you hear is different from the voice heard by others, so the voice in the tape recorder is the same as the voice heard by others.

People usually hear their own voices, not only from their ears, but also through the vocal cords that vibrate the brain and through the bones and muscles to the ears, while with a tape recorder, the sound heard is only transmitted from the air to the ears. This makes the pitch of the voice different, but the sound you hear in the tape recorder is the same as when others hear you talking.

Sound travels in the air in the form of "longitudinal waves".

A longitudinal wave is a wave in which the direction of vibration of a particle is coaxial with the direction of propagation. For example, when a gong is struck, the direction of vibration of the gong is consistent with the direction of propagation of the wave, so the sound wave is a longitudinal wave. Longitudinal waves are a type of wave (fluctuations are divided into transverse and longitudinal waves).

Also known as "dense waves", the propagation process of longitudinal waves is the appearance of different dense parts along the direction of the wave.

Others hear different voices than recordings. The sound heard is transmitted by air vibrations, and the recording is the sound that is converted by sound and electricity and then played back, so it is slightly different from the sound produced by air vibrations. Sound is a sound wave produced by the vibration of an object.

It is a wave phenomenon that propagates through a medium (air or solid, liquid) and can be perceived by the auditory organs of humans or animals. <

If it travels through the air, the sound is affected by the environment and the timbre changes. The voice of the ** in the recording is equivalent to your voice heard by others. And everyone hears their own voice, which is the result of a mixture of air conduction and bone conduction, through this combination, the energy and timbre of the voice are much less attenuated, which will make people feel that their voice is lower and louder, which is different from recording.

WeChat is one of the social software commonly used by people nowadays, and many people will play back their voices after sending voice to check whether the message is missing. At this time, many people have questions, why is their voice recorded by WeChat voice different from what they usually hear? Not only is it not like its own voice, it is somewhat unfamiliar, and even a little unpleasant.

But if you ask your friends, they'll say that's your voice. And the wonderful thing is that the voice of someone else is the same as his voice in the recording. What's going on?

In fact, not only WeChat voice, but also people have similar feelings when they play ** or K song. Whether you are singing or talking, your voice is not the same as the voice recorded by the recording equipment.

Let's start with how we hear sounds. People listen to sounds by ear, first, the sound from the outside world causes the eardrum to vibrate, and the signal generated by this vibration is transmitted to the auditory nerve through the ossicles and other tissues, and then the auditory nerve transmits the signal to the brain, and the person hears the sound.

The transmission of the signal generated by the vibration to the auditory nerve is related to the propagation medium of sound: one of the mediums that humans need to hear sound is the human skull and jaw, and this sound conduction mode is called bone conduction, also called bone conduction. The other medium is air, through which sound is conducted, also known as air conduction.

More specifically, sound travels in the air in the form of waves, which we often call sound waves, which cause the eardrum to vibrate and transmit to the auditory nerve. Two different modes of propagation carry sound to the inner ear, and the ear will have different impressions of the energy and timbre of the sound, so people hear different sounds.

Specifically, if it is transmitted through the air, the sound will be affected by the environment, the energy will be greatly attenuated, and the timbre will also be changed. When we listen to our own voice in WeChat or recording, it is equivalent to your voice heard by others, which is the sound of air conduction, not the sound heard through bone conduction.

The sound that everyone hears is the result of a mixture of air conduction and bone conduction, part of the sound is transmitted by air to the ossicles, and some of the sound is transmitted to the skull through the throat and directly vibrated to the inner ear. With this combination, the energy and timbre of the sound are much less attenuated, which will make people feel that their voice is lower and louder, which is different from the sound heard and recorded by others.

There are also people who feel that listening to their own voice in the recording is very difficult, in fact, it is not unpleasant, but because the recording can only be transmitted through the air, which is different from listening to their own voice normally, we are not used to it.
