Why doesn t the tape recorder feel like its own voice when it plays out its own recordings?

When a tape recorder plays out its own recordings, it doesn't feel like its own voice because the sound we hear from the tape recorder travels in a different way than the sound we make ourselves. The specific analysis is as follows:

Probably everyone will feel that their voice is impeccable. But in reality, the sound you hear yourself speak in a very different way than what others hear;

Many people can hear their voices from the tape recorder. Almost everyone who hears it will say, "This is like the way I speak!" In fact, this voice is really your original voice. It is caused by the different transmission channels of sound waves;

When the sound transmitted through the air is affected by the environment, its energy will produce a large amount of attenuation, and its timbre will also change, when it reaches other people's ears, it will pass through the outer ear, eardrum, middle ear, and finally enter the inner ear, this process will also have an impact on the energy and timbre of the sound;

The sound transmitted through the skull passes directly to the inner ear through the bone between the throat canal and the ear, and the attenuation and change of sound energy and timbre are relatively small. Therefore, there will be a certain difference in energy and timbre between listening to your own voice and hearing your own voice through a tape recorder.

Because of the different mediums of transmission, when we speak to others, our own voice is transmitted through our skulls to the eardrums.

You can learn this knowledge in physics in the first semester of the second year of junior high school.

That's very likely, the general recorder recording effect is poor, there is a lot of distortion, to have a high-quality recording effect, or need professional equipment to be competent.

Why is my own voice weird in the recording? Which is the real voice?

Yes. Due to the phenomenon of bone transmission, hearing one's own voice is different from others hearing one's own voice, soAudio recorderThe voice is the same as what others hear.

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 in the air is in the form of "longitudinal waves."

forms of propagation.

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 waves.

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.

Because the medium of propagation is different. When we are with others.

Bai speaks,

That's normal, we.

Listen to your own voice.

It is through the vibrations in the ear, and listening to the outside world is through.

The eardrum vibrates, so it's not the same, to use a simple analogy, like in a room.

Listen to the people in the house. Talking is the same as speaking from someone outside the house.

Why does it not feel like my own voice when listening to my own recordings? What others hear.

The reason why recording is not like your own voice is because there is a certain difference in the way the two are transmitted, we listen to our own voice, most of them are transmitted through bones, and when we hear the sound in the tape recorder, it is transmitted through the air, and the sound in the tape recorder is equivalent to the sound of others hearing you, which is not the same as hearing yourself.

The reason why the recording is not like your own voice.

With the improvement of modern science and technology, we can use many technologies to retain our previous image and words, such as cameras, tape recorders, etc., which bring certain convenience to our lives, but sometimes when we use the tape recorder, we will find that the sound it records is different from the voice we usually hear.

The reason why I feel that the sound of the recording is not like my own voice is mainly because the sound is transmitted in different ways, because most of the voices we hear are transmitted through the bones, while the voice of our own voice in the tape recorder is transmitted through the air, so there will be a certain difference.

Generally, if it is transmitted through the air, the sound will be affected by the environment and change, and the sound in the tape recorder is similar to the sound of others listening to you, and listening to your own voice is the result of air and bone transmission, so you will feel lower and louder.

Why do you find that the sound doesn't sound like your own when you listen to the voice in the tape recorder? I don't know if there is such a doubt, but sometimes we are surprised to hear our own recordings and feel that Senling is not our own voice. I watched my own **, and when I heard my own voice in it, I felt that it was not my own voice, but it was different from my own.

Looked into it, yes. There are two ways for people to hear sound: through the air and through the ear bones. Every time I hear a recording of myself, why do I feel like we are not my own voice?

Air conduction. When we make a sound, the sound we make passes through the air, and then through the ear canal, the eardrum, into the other person's auditory system. Due to the long distance of air transmission and many obstacles, the attenuation and timbre become lighter in the process of sound propagation.

When we record, the sound is airborne, and so is when others hear us.

Osteometic conduction. When we make sound, it also travels through our brain bones and through our ear bones into our ears. Because the propagation distance of the ear is relatively close, it is the propagation of a hard medium (referring to physical knowledge, the sound propagation of steel pipes is faster than that of air), the propagation speed is also fast, and the attenuation is relatively small, so the sound heard by the ear is very macroscopic and powerful.

Because we ourselves have heard that our voices are bone conducted, sometimes do you feel that you sing well on your own? Others, however, are not. I can't believe it, now grind my teeth and try it myself.

Isn't it only you who can hear it?

Therefore, when we speak, there is both air conduction and bone conduction of this family. We ourselves hear sounds that are conducted by bone, while others hear sounds that are conducted by air. The timbre is faint, and the tape recorder is also recording airborne sound.

So when you listen to your own recordings, not your own voice, but you feel different from what you've been listening to. Sound is divided into two pathways of propagation. The sound produced by the vocal cords passes through the mouth, the fluctuations of the sound are transmitted from the surrounding environment to the ears, the eardrum vibrates to hear the sound, and when listening to the recording, it is transmitted through the air.

After vibrating from the vocal cords, bone vibrations from the head travel into the ear canal, causing the eardrum to vibrate, allowing us to hear sound. When we hear our own voice, we hear it through our bones. So, listening to your own voice is actually a two-way process.

Because the two sounds we hear travel through different mediums, we don't feel like our own voices.

Because the sound changes in the process of propagation, then the sound of the tape recorder will also change more or less.

Because it's changed. The sound in the tape recorder has been processed so that it is not exactly the same as the original.
