The sound, the feeling is different from before, and it has changed a lot. What happened?

If you know something about acoustics in physics, then you will understand that this is actually because the skull transmits sound!

This is because the propagation channels of sound waves are different. The external sound heard by the human ear is the vibration of the external air, which transmits the sound information to the auditory nerve through the eardrum, and the processing of the brain forms what we call hearing. The sound we hear when we speak by ourselves is directly transmitted from the skull to the auditory nerve, which is processed by the brain to form another kind of hearing.

In other words, the former let others hear the sound through air transmission; The latter spread through the skull and let himself hear the sound.

Why are these two ways of communication so different? In fact, this is because the air-borne sound is affected by the environment, and its energy will be greatly attenuated, which will lead to great changes in timbre. Moreover, when the sound reaches the inner ear of others, it will also pass through the outer ear, eardrum and middle ear, which will also have an impact on the energy and timbre effect of the sound. The sound transmitted through the skull directly reaches the inner ear through the bone between the throat and the ear, so the attenuation and change of sound energy and timbre are naturally small. So the hearing caused is different.

Recording is like others hearing your voice. In fact, others are used to your voice, and because you have been used to listening to your own voice through the skull for a long time, others will not think that the tone of your voice has changed, but that you are ugly and strange ~

Give the simplest example. Have you ever eaten cookies? It's easy to finish eating. When we eat cookies, do we find that there is a loud chewing sound when we chew, but others hear it very quietly? This is because of the difference between skull sound transmission and air sound transmission.

In fact, I also think that my voice sounds good through the skull, but the voice that happened in the tape recorder is very ugly. But others don't think so, because when we talk, we all hear each other through the air. Just like when you listen to the voice of a person with a beautiful voice, you think he speaks beautifully, but in fact he will feel the same as you and think he speaks badly.

This is normal. Almost everyone feels this way. Don't worry!
