As we all know, every boy will have a voice change period. We know the symptoms of boys' voice change, so we must attach great importance to them. Do you know what the symptoms of boys' voice failure are? Come and have a look with me.

The symptom of boys' voice change failure 1 1, voice change is an inevitable stage of growth, and people's voice will change from children's voice to adults' voice.

Usually study begins at the age of 12- 13 and ends at the age of 17-28. Diet and environment also have a certain influence, and individuals are prone to change their voices.

2. After entering this period, people's throats began to develop rapidly forward, backward, up, down, left and right.

Male thyroid cartilage will protrude forward to form an Adam's apple, while female's up-and-down extension shows that the protrusion of larynx is not obvious, which is a big difference between men and women after voice change.

3. The voice became stiff and lost the softness of the child. The vocal cords are ruddy, congested and thickened, and various gaps are formed between the two vocal cords (glottis), especially the third part behind the glottis can not be closed, forming a triangular gap, that is, the voice change triangle.

This is a very common situation, and at this time the sound is easily damaged and must be protected.

4. After the voice change, the male voice drops by 8 scales, and the change is obvious; Female voice is lowered by three scales, and there is little difference in treble, but there is obvious difference in timbre with children.

5. Teenagers generally start learning languages between the ages of 14 and 16.

This period is a critical period for the development of the larynx and vocal cords. The main symptoms are hoarseness, narrow vocal range, weak pronunciation, local congestion and edema, and increased secretion.

6. Generally, the time of sound change is six months to one year.

If you want to maintain your voice well during the voice change, besides paying attention to the scientific and reasonable use of your voice and not making it too tired, it is also important to adjust your diet.

7. First of all, we should pay attention to supplement collagen and elastin.

The main components of sound generator are larynx, Adam's apple and thyroid cartilage, all of which are composed of colloid and elastin. Vocal cords are also composed of elastic membranes. Therefore, teenagers should eat more foods rich in collagen and elastin, such as pig's trotters, pigskin, tendons, fish, beans and seafood.

The second is to take B vitamins and calcium.

Vitamin B2 and vitamin B6 can promote skin development, while calcium can promote thyroid cartilage development.

Foods rich in vitamins include celery, tomatoes, eggs, beans, animal livers and fresh fruits. Foods rich in calcium are mainly fish and shrimp, milk and bean products.

The above content introduces the symptoms of male tone sandhi for us. By understanding these symptoms, we can effectively judge and choose whether to enter the voice change period during the male voice change period, so as to take effective and targeted treatment, and at the same time help us better spend the voice change period and prevent improper measures from hurting our voices.

Signs of boys' voice change failure 2. Voice change is a necessary stage of growth. With the growth of age, people's voice will change from children's voice to adults' voice. Generally, the voice change starts at the age of 12- 13 and ends at the age of 17-28. Food and environment also have a certain influence, which is easy to cause individual changes in voice.

Entering this period, people's throats begin to develop rapidly forward and backward, up and down, left and right. Male thyroid cartilage will protrude forward to form an Adam's apple, while female extends up and down to reveal that laryngeal protrusion is not obvious, which is a big difference between men and women after voice change.

The voice hardens, losing the softness of the child, and the vocal cords turn red, congested and thickened. There will be various gaps between the two vocal cords (glottis), especially the back third of the glottis, which cannot be closed to form a triangular gap, which is called the voice change triangle. There are many such cases. At this time, the sound is easily damaged, so we must pay attention to protection.

After the voice change, the male voice will drop by 8 scales, and the change is obvious; Because women have dropped three scales, there is little difference between high and low notes, but the timbre is obviously different from that of children.

Teenagers generally enter the voice change period at the age of 14- 16. This period is the growth and development stage of their larynx and vocal cords. Its manifestations are hoarseness, narrow vocal range, weak pronunciation, local congestion and edema, and increased secretion.

Generally, the voice change period is six months to one year. If you want to maintain your voice well during the voice change period, besides using your voice scientifically and reasonably, it is also very important to pay attention to your diet.

First, we should pay attention to the intake of collagen and elastin.

The vocal organs are mainly composed of Adam's apple, Adam's apple and thyroid cartilage, which are composed of mucin and elastin. Vocal cords are also made of elastin membranes. Therefore, teenagers in voice change period should eat more foods rich in collagen and elastin, such as pig's trotters, pigskin, tendons, fish, beans and seafood.

Second, we should take B vitamins and calcium.

Vitamin B2 and vitamin B6 can promote the development of skin; Calcium can promote the development of thyroid cartilage. Foods rich in vitamins mainly include celery, tomatoes, eggs, beans, animal livers and fresh fruits. Foods rich in calcium mainly include fish and shrimp, milk and bean products.

Third, staple food and non-staple food should be soft and fine.

Don't eat fried peanuts, popcorn, crispy rice, nuts and fried hard food to avoid mechanical damage to your throat.

Fourth, drink more water.

It can reduce or eliminate local secretions and avoid secondary infection.

Fifth, eat less sour, bitter, cold and spicy food.

Such as garlic, pepper, ginger, leek and so on. Because these foods will irritate the trachea, larynx and vocal cords. Don't drink too hot boiled water or too many cold drinks. Too cold or too hot is not good for vocal cords. Alcohol and tobacco should be avoided to avoid aggravating local discomfort.

Bacterial inflammation.

Sixth, chew slowly when eating. Don't eat too fast, but also beware of sand and fishbone in food stabbing throat tissue.

Before puberty, there is little difference in pronunciation between boys and girls, but after puberty, there will be obvious differences. Boys, in particular, will be a little hoarse when they speak, commonly known as "broken voice." When you look closely, you will find that the boy's Adam's apple has become bigger, but it is not very prominent. This stage is called voice change. After a while, the boy's voice will change from a child's voice to a deep voice, similar to that of an adult male, and the Adam's apple will be obviously prominent. Adam's apple and voice change are closely related.

During adolescence, the development of the human body changes greatly, and the development of the larynx is also very rapid. The larynx is mainly composed of upper thyroid cartilage and lower cricoid cartilage. Thyroid cartilage is formed by connecting the left and right cartilages at the midline, and its shape is like a two-page book cover spread backwards. The vocal cords are located in the thyroid cartilage. After the boy enters adolescence, the larynx grows rapidly, the angle of left and right cartilages becomes smaller, and the upper part protrudes forward to form the Adam's apple. At this time, the front and back necks of the larynx also widened rapidly, the length of vocal cords almost doubled, and the width and thickness also increased. With the development of vocal cords, from the audio point of view, it will be reduced by about an octave, so the child's voice will become a deep male voice. The average boy 13 years old began to change his voice, and 15 years old has completely changed his voice. After 19, all boys have prominent Adam's apple and their voices become thicker.

Although there is no obvious change in the appearance of the girl's Adam's apple in adolescence, there are obvious changes in the Adam's apple: that is, the vocal cords become longer and narrower, so the pronunciation frequency is high and the tone is high and sharp.

The length of the voice change period varies from person to person, ranging from 4 to 6 months to about a year. During the voice change period, the vocal cords have undergone obvious changes, such as congestion, swelling and increased secretions, which are easy to be damaged. Therefore, in order to protect their voices, teenagers in this period should not scream loudly or talk loudly for a long time. Try to avoid the stimulation of external adverse factors, do not smoke, do not eat irritating food, do a combination of work and rest, actively participate in sports activities, and prevent colds and colds. The length of the voice change period is also closely related to the geographical location. Children in the south are shorter, about 4~7 months, and children in the north are longer, about 6~ 12 months!

Signs of boys' voice change failure 3 After puberty, the vocal cords of boys and girls have gradually changed obviously. The boy's vocal cords grew from 6-8 mm in childhood to 20-24 mm, and also became wider and thicker. Girls' vocal cords gradually grow to 15- 18 mm, and at the same time they are relatively narrow. As a result of these changes, the voices of boys and girls have changed obviously, and the childish voices have gradually disappeared. Boys' pronunciation frequency is low, and their tones become thicker and deeper; The girl's pronunciation frequency is high, and her tone becomes high and sharp. This period of change is called the voice change period.

Some boys have a strong voice change, so that the voice is slightly rough, cracked and falsetto, commonly known as "broken voice". In fact, this is only a temporary normal physiological phenomenon. Don't worry, it usually takes six months to a year. During the voice change period, the rapidly developing vocal cords will have mild inflammatory edema. If there are bad external stimuli, it is easy to cause permanent damage to the vocal cords and affect the voice of adults.

Therefore, male and female teenagers should pay attention to protecting their voices during the voice change period. That is, pay attention to the hygiene of singing, don't sing loudly or for a long time, "hang your voice", and don't eat sour, spicy and irritating food; Do not smoke or drink; Drink more boiled water, light tea or soak (stir-fry) chrysanthemum, Ophiopogon japonicus and boat-fruited Sterculia water. The boy's voice change period and hygiene During the adolescence, the boy's voice will change from a childish voice to a deep male adult voice. This period is called the voice change period. At this time, if you don't pay attention to protecting the vocal cords, it is easy to be dumb. The voice change period is something that both boys and girls will experience in adolescence.

Generally, boys' voices begin to thicken at the age of 13, and develop at the age of 18. Because boys develop a unique Adam's apple, the change of voice change period is more significant than that of girls. Why do adolescent boys have obvious voice changes? We know that human pronunciation mainly depends on the vibration of vocal cords, and the vibration of vocal cords is related to the development of larynx.

The morphology of human larynx is mainly composed of upper thyroid cartilage and lower cricoid cartilage. Thyroid cartilage consists of two square cartilage plates, left and right, which are combined in the middle plane to form the front wall and two side walls of the larynx. The front edges of the two plates are connected at the front midline, and the upper end of the plate protrudes forward, which is called Adam's apple. Adult males are particularly prominent, which can be clearly seen on the body surface. The vocal cords of pronunciation are located in the laryngeal cavity here.

After entering adolescence, the boy's larynx develops rapidly due to the action of androgen, and the angle formed by the left and right cartilages becomes smaller and protrudes forward, forming a unique Adam's apple for men. The anterior and posterior diameter of the larynx also widened, and the vocal cords located in the thyroid cartilage also grew, widened and thickened at the same time. The voice of this issue is gradually decreasing in audio, so the boy's voice has gradually changed from the original children's voice to a rough and deep voice.

Because the amount of male hormones secreted by girls is small, the throat development is not obvious, and there is generally no Adam's apple, so the voice continues to be high. During the voice change period, there may be symptoms such as fragile texture, narrow range, hoarseness and abnormal pronunciation. During the examination, congestion, swelling and increased secretion of vocal cords can be found.

Therefore, special attention should be paid to protecting your voice during the voice change period, otherwise it will make sip hoarse, and you will not be able to sing sweet songs and make crisp sounds all your life. During the voice change period, we should protect the vocal cords and do a good job in health care.

Please note the following points:

1. During the voice change period, you should be temperate in singing and speaking. If you raise your voice and shout loudly or sing high notes for a long time during the voice change period, it will cause congestion, inflammation, vocal cord hypertrophy or vocal cord dysfunction, so excessive vocal practice during the voice change period is easy to damage your voice. Generally speaking, girls should not do too intense or excessive vocal exercises before 17 and boys before 18. Singing time should not be too long, pay attention to proper rest and avoid excessive fatigue of vocal cords.

2. After singing, talking loudly or talking for a long time, don't drink cold water or cold drink immediately. It is best to use warm water.

3. In the cold season, it is best to protect the neck with a scarf or turtle neck to prevent colds, colds and upper respiratory tract infections.

4. In terms of diet, try to eat less food that is irritating to sound, such as pepper, garlic and fried food. Smoking and drinking will also affect the development of vocal cords and should be quit.

In the period of voice change, boys should pay special attention to protecting their voices, otherwise they will make their voices hoarse, not only unable to sing good songs, but also difficult to speak at ordinary times.

To this end, we should pay attention to the following issues:

First, control the volume. Most boys love singing, but it is not advisable to sing for too long at a time during the voice change period, especially for high-pitched and strong-pitched songs. It is not advisable to talk loudly during games or sports, and it is not advisable to talk loudly in windy weather and dusty environment. Don't drink cold water or cold drink immediately after singing. It is best to drink warm water.

Second, keep warm. When going out in cold season, you should pay attention to protect your neck with a scarf or turtle neck to avoid catching cold, especially to prevent upper respiratory diseases such as colds.

Third, don't be too tired. Teenagers are energetic, prone to excessive activity and overwork, which will reduce the body's resistance, thus causing inflammation of vocal organs such as laryngitis and tonsillitis or systemic diseases.

Fourth, control spicy and greasy food. Fifth, timely treatment. If you feel itchy or hoarse, you can make tea with some Chinese medicines such as boat-fruited Sterculia and Ophiopogon japonicus, or take throat moistening tablets, iodine throat tablets and Dumifen buccal tablets. In the event of upper respiratory tract infection and acute pharyngitis, you should seek medical advice as soon as possible, and talk less and don't talk, so that the vocal cords can be fully rested.
