What is the basic process by which people perceive sound? ？？

People's perception of sound is the process of hearing. The process of hearing is a complex physiological process, which includes 3 basic processes:

1) The transmission of sound waves in the ear.

2) The process by which the mechanical vibrations caused by sound waves are converted into bioelectrical energy during the transmission of sound waves, and at the same time, nerve impulses are generated through the release of chemical transmitters.

3) The process of comprehensive processing of incoming information by the auditory center.

Sound waves are transmitted to the inner ear through two pathways: air conduction and bone conduction. Under normal circumstances, air conduction is the main thing, that is to say, the sound waves are transmitted to the inner ear through these two ways to excite the hair cells in the Curti organ, and the hair cells are in contact with the endings of the auditory nerve, and the hair cells are excited to stimulate the release of chemicals, so that the cochlear nerve is impulsed. Impulses are transmitted to the brain through the cochlear nerve conduction pathway, and through the comprehensive analysis of the auditory center of the cerebral cortex, we finally feel the sound, that is, hear the sound.

The ear is made up of three main parts: the outer ear, the inner ear, and the middle ear.

Outer ear: Sound waves from the outside world are collected by the outer ear, which is made up of the pinna and ear canal. When sound enters the ear, the ear canal increases the loudness of ordinary sounds, making it easier to understand.

At the same time, the ear canal protects another important part of the ear: the eardrum. The eardrum is a round, elastic membrane that vibrates when sound waves hit it.

Middle ear: The vibrations of sound waves are transmitted all the way to the middle ear. The middle ear contains three tiny bones called ossicles.

They are commonly referred to as malleus, incus and stapes. They build a bridge from the eardrum to the inner ear. They raise the sound up, increasing the vibration of the sound until the sound waves reach the inner ear safely through the elliptical window.

Inner ear: The inner ear, also known as the cochlea, is a snail-like, ring-shaped shell covered with a series of fluid-filled tubes. As the sound waves pass through the oval window, the fluid begins to move, causing the tiny hair cells to follow suit.

These hair cells then convert vibrations into electrical impulses that are transmitted along the auditory nerve to the brain.

Each part has its own specific function, and they allow sound waves to enter the ear and be converted into electrical impulse signals that the brain can understand. The outer ear collects sound waves and sends them directly to the middle ear. After that, the middle ear amplifies these sound signals and transmits them to the inner ear.

The inner ear converts the vibrations of sound into electrical impulses, which are transmitted along the auditory nerve to the brain.

The functions of the various parts of the ear and the process of sound conduction are as follows:

1. The sunken pinna can gather and reflect sound waves, so that the sound is enhanced, and transmitted to the external auditory canal.

2. The S-shaped external auditory canal refracts sound waves, which can slightly enhance the sound and transmit it to the eardrum.

3. Sound waves cause vibration of the eardrum.

4. The ossicle bones (malleus, incus, stapes) in the middle ear feel these vibrations and make the sound unable to amplify in the original mode, thereby reducing the damage of loud voices to the inner ear.

5. The vibration reaches the cochlea through the oval window, and the internal flow speed is set during operation. This allows specific nerve cells to convert sound waves into electrical impulse signals.

6. The auditory nerve sends these electrical impulses to the auditory center (brain), where these signals become audible sounds.

The sound from the outside world causes the eardrum to vibrate, which in turn causes the ossicles to vibrate, which in turn transmits to the auditory nerve through other tissues. Please refer to the following articles.

Sounds from the outside world cause the eardrum to vibrate, and this vibration is transmitted through the ossicles and other tissues to the auditory nerve, which transmits signals to the brain so that the person can hear the sound.

The process by which the human ear perceives sound is the process by which the sense of hearing is produced. The process of hearing is a complex physiological process, which includes three basic processes: (1) The transmission process of sound waves in the ear. (2) Sound waves in the process of transmission.

The basic process of perceiving sound is as follows: the sound from the outside world causes the eardrum to vibrate, and this vibration is transmitted to the auditory nerve through the ossicles and other tissues, and the auditory nerve transmits the signal to the brain, so that the person hears the sound.

The basic process by which we perceive sound: the sound coming from the outside world causes the eardrum.

Vibration, this vibration is transmitted through the ossicles and their tissues to the auditory nerve, the auditory nerve.

Signals are transmitted to the brain so that people hear the sound.

First, sound waves are generated by mechanical vibrations of the sound source, and the sound waves are transmitted to the human ear through an air medium. The human ear is a sensory organ. Sound transmission is estimated by the ear, and the signal of sound can be sensed and transmitted to the brain in a bioelectric way.

The brain centers are then analyzed and then bioelectrically transmitted to the effectors (e.g. ears, hands, feet). At this time, some ears will move,,, or pass to the hands (too loud and the hands will block the ears). For example, command feet (run when you hear the beast coming) and so on.

According to the definition of air conduction vs. bone conduction, people can hear sound in both ways

So the answer is: air conduction; Bone conduction

The frequency at which humans perceive external sounds depends mainly on the following:

Depends on the nerve impulses caused by the part of the traveling wave that can reach. The lower the frequency of the segment, the farther it will be transmitted.

So the answer is: air conduction; Bone conduction

The sound must be vibrating, the sound is transmitted to the human ear through the air, and the sound will cause the vibration of the eardrum, and then it will be transmitted to the brain through the auditory nerve to produce hearing;

Workers wear noise-proof earmuffs to attenuate noise at the receiving point of noise (i.e., the human ear);

So the answer is: vibration, air, eardrum, human ear

Answer C analysis: The key to solving this problem is to know that sound is produced by the vibration of objects, and the human ear hears sound through the eardrum, ossicles, auditory nerve, and finally to the brain

Answer: Sound will cause the eardrum to vibrate, and this vibration will be transmitted to the auditory imaginary nerve through the ossicles and other tissues of the auditory plexus, and then to the brain, so the person will finally hear the sound;

Therefore, choose C Comment: This question tests students' understanding of the process of perceiving sound by the human ear, and is a basic question

The sound causes the eardrum to vibrate, and this vibration is transmitted to the auditory nerve through the ossicles and other tissues, and then to the brain, so the person will finally hear the sound;

Therefore, C
