The sound is a way to understand the world. Yangchun Baixue in the music hall, and the small tunes between the villages between the countryside. Under the singing of different people, it is exciting. And this difference is brought by "voice". Just as the appearance characteristics can make you know, we can also distinguish a person through the voice, and the police can also judge the authenticity of the voice through criminal investigation.

Voice is a business card for human voice, and it is also one of the main ways for human communication and information transmission. In life, people also have different calls for their voice.

How do you make your voice?

When you say the phrase "everyone has their own unique voice", there is a process that has five parts of tissue organs in your body and it is not easy to participate in. The reason why the voice can convey the phonetic semantics is that the power organs, vibration organs, resonance, and sound -structured organs are completed together under the coordination of the nervous system.

The brain will coordinate brain stem reflection, lung function, chest wall compliance, throat, pharynx, nose, and oral regulation. Under the regulation of the high -level center, each part of the organs performed their duties and cooperated with each other. The power organs are achieved through the cooperation of the respiratory system (pulmonary, trachea, respiratory muscle, thoracic, etc.). The airflow we exhaled will form under the door pressure and promote vocal vibration.

As we all know, the voice is produced by vocal cords, and the participation of vibration organs is indispensable. The vocal cord is an organization with a complex and exquisite layered structure. The related diseases can cause hoarseness and even sound.

The addition of resonance organs makes everyone in the world different from each other. The sound from the throat causes the resonance cavity (chest cavity, pharyngeal cavity, oral cavity, nasal cavity and sinus) to vibrate. What is even more amazing is that the length and shape of the resonance cavity can be adjusted, and after tension, the sound will produce different effects to meet people's expression needs. A series of pan -sound and recharge will form, and sound, sound and sound. It can be said that the factors that cause your unique voice are the three major differences: the natural structure of the vocal cords and resonance systems is different; the muscle regulation ability is different; the use skills of the resonance system are different.

Language is the tools for thinking and people to communicate with people, but before the popularity of Mandarin, "ten miles different sounds" are extremely common. Such differences are brought by the audio organs. The tone organ includes lips, tongue, teeth, palate, and jaw. By regulating the mutual position of the audio organs, different voice interpretations, such as changing the shape and size of the oral cavity, affecting the channel airflow, and emitting vowels and consonants. phoneme. When we pronounce, we can experience this difference. For example, the position of the tongue changes when the tongue sounds.

Different age, why is the sound different?

As people grow older, our voice will change. At 3 months, the fetus basically completed most of the anatomical structure of the throat, and the development of the throat was significantly significantly in the first three years after birth, and the change was less after 6 years old. This stage, which is what we call the "child voice stage", is characterized by the bright tone, the tone is higher than the adult, but the width and the richness of the sound range and the richness of the sound are lower than that of adults. At this time, the human vocal cords and the entire sound system did not fully develop.

In childhood, the voice of men and women is similar because the throat development and the length of the vocal cords (about 6 ~ 8 mm) are similar to thickness. With the arrival of adolescence, the sound changing period of child voice transition to the adult has begun. At this stage, the sound system and the various systems of the whole body developed rapidly. The adolescent voice changed greater and gradually had gender differences. Thinning.

Specifically, at this stage, the girl's throat becomes narrow, the vocal cord becomes short and thin, the length is 15-20 mm, and the vibration frequency is high; The length is 20 ~ 25 mm. Generally speaking, girls change their voice from 10 to 18 years old, starting from 8 to 15 years old, 12 to 16.5 years old; boys' average voice changing age is 11 to 15 years old. After passing the sound change period, human voice will not be fixed here, and the sound will be aging.

After age, people's voices will become soft and dumb. This is because the soft tissue in the throat is weakened, affecting the sound quality, loudness and quality of the sound. Human voice has been going downhill since the age of 65. At this time, women's voice became more and more dumb, the sound quality is getting lower, and the sound of men is getting weaker and weaker, and the sound quality is getting higher and higher.

How to protect our throat?

The aging of the voice is an irreversible change, but in daily life, protecting our throat can not be ignored. Many people in the world are tortured by the diseases that are disturbed by voices. In life, chronic laryngitis, vocal cords, vocal cords, polyps, etc. are more common voice diseases, hoarse sounds, low sounds, rough sounds, etc. Occupational people who need to use the voice for a long time are the hardest hit areas of the disease. So it is necessary to protect the throat.

If you want to have a good throat, physical and mental health is the basis. A healthy and strong body and positive psychological state will naturally bring a good state to the throat. Many people also have the habit of clearing the throat. In fact, this behavior not only hurts the laryngeal mucosa, but also causes the tension of the throat muscles. When the throat is uncomfortable, you can choose to drink warm water or relax. At the same time, pay attention to the scientific throat. When breathing, use the nose to inhale more instead of using the mouth. People who breathe long for a long time will have sore throat and dryness; maintain a suitable loose clothes, so as to give the thoracic movement and breathing amplitude enough to sufficient enough Space. In daily life, we can also refer to the singer's throat maintenance method, such as the famous Peking opera performance artist Mr. Mei Lanfang to protect his throat is a light diet and seven or eight meals. The spicy diet and unauthorized overeating can constantly stimulate the throat mucosa, which is a recurrence button for patients with chronic laryngitis.

The environment of people's living and living is also very important. Ventilation and good residences, clean and warm and humid air, are good for the health of the throat.

In addition, an important point is not to smoke, and try to stay away from second -hand smoke. Tobacco can be said to be a throat killer. Tobacco smoke particles are 50,000 times more than the particles in ordinary air. Burning half -cigarette can allow the indoor PM2.5 to reach the level of extremely severe pollution. In such an environment, the throat will be violated by harmful substances.

A large amount of cilium toxin contained in tobacco and solidifying the mucus can cause problems such as mucosal mucosa and hypertrophy, which will cause thrombosis, tissue hypoxia, and permeability to decrease the capillaries of the vocal cords. The vocal cord gradually shows the appearance of the "smoky vocal cord", the luster and elasticity are reduced, and the edges are no longer sharp. What is even more terrible is that the thickened epithelium may occur in different types, leading to laryngeal cancer. Therefore, smokers need to quit smoking, and people who do not smoke also say NO to second -hand smoke and stay away from smoke.
