How does the brain process the transmission of sound and information? Do you know? The transmission of sound information can be very different from what we think. individual sound information, such as sound frequency; Then, the superior temporal gyrus extracts the transmission of the most important line information of the language; Nervous system.

Constantly adapting to the brain by integrating information from different functional systems. But how effectively the brain organizes the efficient processing of neural information locally and across the brain to support the integration of sounds from simple symbols such as consonants and vocals.

The sound comes from the outside world. All information from the outside world is transmitted through sensory nerve channels, which are processed synchronously in the process of transmitting information. That's the basic pattern.

Sound is language, language processing is done in the process of propagation, sound is **, **processing is done in the process of propagation. In other experience modes, other sounds are processed during the delivery process. The sound is like a keyboard.

It's just a way to enter. Language represents a certain type of information, whether external or internal, and each information has its own fixed link processing path.

Send it to the temporal lobe located.

of the auditory cortex. It can receive sound information, the eyes can receive image information, and the nose can receive olfactory information. This information is transmitted by the nervous system to the brain, which elaborates on it.

Therefore, the human body itself is a multi-information processing cortex, which processes simple sound information, such as the frequency of sound.

The superior temporal gyrus extracts more important features, such as consonants and vocals, and converts sounds into meaningful words. However, for a long time, there was a lack of direct evidence for this theory, and language processing took place in parallel, contrary to the old theory that the brain processes sound information and then converts it into verbal information. When the sound of speech reaches the ear, it will pass from the cochlea.

It is converted into an electrical signal and sent to the sensory cortex. The processing of language follows a continuous path: first, the processing of the primary auditory cortex is the operating rule of the human brain for processing language sounds.

There are many reasons for hearing loss, and from the perspective of the patient, there are roughly as follows:

1.The external auditory canal is blocked, the sound waves cannot reach the eardrum or the eardrum is perforated in a large area, and the eardrum cannot vibrate;

2.The middle ear ossicles are impaired in their mechanical conduction system, preventing tympanic membrane vibrations from being transmitted to the cochlea of the inner ear;

3.The cochlea of the inner ear is damaged, so that the vibration waves cannot be converted into nerve impulses (signals) to be transmitted to the ear nerve;

4.impaired nerve conduction from the auricular nerve to the auditory center of the occipital part of the brain;

5.The auditory center of the brain is damaged and cannot ultimately be analyzed to produce hearing.

Loss of hearing may result in a ruptured eardrum or a disorder of the auditory nerve.

At this time, the sound heard by people is transmitted to the auditory nerve through bones such as skull and jaw, and then transmitted to the brain by the auditory nerve, this way of hearing sound is called bone conduction, and the hearing aid uses the principle of bone conduction;

During the whole process of sound transmission to the brain, any part of the body is damaged, the person will lose hearing, but if it is only a conduction disorder, such as damage to the eardrum (ossicles), and the auditory nerve is not damaged, bone conduction can be used to hear sound

So the answer is: eardrum (ossicles); auditory nerve; bones

The human brain is similar to a computer, so let's use a headset as an example to explain this process!

The sound vibrates the microphone diaphragm through the air (in the human ear, the eardrum vibrates), and then drives the voice coil to cut the magnetic field lines to generate audio current (the human ear is more complex than this, several ossicular bones cause the cochlea to vibrate, and the auditory nerve converts the vibration into nerve impulses). The audio current is transmitted to the computer through a wire, and the data is processed by the CPU (the nerves transmit impulses to the brain), and the computer picks up the sound (and the person hears the sound). Computers are dead, people are alive.

Computers will only process sound according to established programs, and people will quickly make corresponding judgments based on the information contained in the sound, which is much more advanced than computers.

The vibration of the eardrum produces biological signals that make people feel sound.

AC, sound can also be transmitted to the auditory nerve through the skull and jaw, causing hearing, this way of sound conduction is called bone conduction Therefore, people can hear sound without ears, so A is wrong, C is correct;

b. Sound is transmitted to the brain through the ossicles, semicircular canals, and finally to the brain through the auditory nerve, so B is wrong;

d. People with auditory nerve damage can no longer perceive sound through other means, so D is wrong so choose C
