Jokes changed their voices.

The child is in a voice change period! The voice change period refers to teenagers aged 12- 16. For boys, the voice change period is generally 13- 16, and it can be completed by 18. Girls are generally 12- 15 years old, and the latest is probably 16 years old. Due to the growth of larynx and vocal cords, hoarse voice, narrow vocal range, tired pronunciation, local congestion and edema, and increased secretion, the voice is different from that of childhood for half a year to a year. The voice change period can be divided into early, middle and late stages. Vocal cords in voice change period: the change of vocal cords is an important manifestation of voice change period. In adolescence, the girl's throat becomes narrow, the vocal cords are short and thin, and the vibration frequency is high, so the tone is high and thin; The boy's throat cavity is bigger, and the vocal cords are wider and thicker, so the tone is deeper and thicker. Vocal cord disease: Because adolescent children like to speak loudly and sing, and they like to show their loud voices anytime and anywhere. I don't know if I don't pay attention, will it hurt the growing vocal cords. The vocal cords are extremely delicate at this time. If the owner does not pay attention, there will be congestion and edema, or vocal nodules or vocal polyps. In light cases, the pronunciation will be tired and weak, and the tone will change. Severe hoarseness and even difficulty breathing, unable to speak. Vocal cord maintenance during voice change: A Usage: Use your voice correctly, and don't abuse your voice too much to shout or speak loudly, especially be careful not to sing too much. Excessive use of voice in adolescence may lead to lifelong hoarseness. B keep warm: avoid catching cold or catching a cold. Pay special attention to keep warm in winter, try not to wear low-necked clothes, and keep your neck warm to avoid catching cold in your mouth and throat. Catch a cold will aggravate the swelling and congestion of vocal cords. Besides paying attention to changing clothes and bedding with the weather, taking part in some sports activities in moderation and doing physical exercise every day will also be of great benefit to the healthy growth and development of vocal cords. C exercise: combine work and rest, live regularly, and ensure adequate sleep. Do not stay up late, and ensure more than 7 hours of sleep every day. Healthy diet and vocal cords: principles: First, do not eat or eat less irritating food, and try not to eat sour, spicy and bitter food, such as garlic, pepper, ginger and leek, because these foods will irritate the trachea, larynx and vocal cords; Second, don't drink too hot boiling water in winter, don't eat too cold cold cold drinks in summer, and don't drink cold water immediately after strenuous exercise; Smoking and drinking are strictly prohibited. The harmful substances in tobacco and alcohol are very harmful to the growth and development of teenagers (including the growth and development of vocal cords); Fourth, staple food and non-staple food should be soft and fine food; Fifth, don't eat fried peanuts, popcorn, crispy rice, nuts and fried hard food to avoid mechanical damage to the throat. The intake of collagen and elastin in the recommended set meal (1). The vocal organs are mainly composed of Adam's apple, Adam's apple and thyroid cartilage, which are composed of collagen 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. (2)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 B 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. How do boys take music lessons when they enter the voice change period? We have been with the children for five years. Not only have we established a profound friendship, but I know every student well. In the second half of last year, I found that some boys were not interested in music, and even some students didn't sing in class. This really worries me. After getting to know each other, I found that our little boy had slowly begun to change his voice. Teenagers generally enter the voice change period at the age of 14- 16. How can they not be old? So I quickly went online to check the information. The situation of boys' voice change period is different. Some boys, about 12, 13 years old, suddenly became louder. And it's like telling the truth and fighting. Belonging to the kind with obvious voice change; Some boys have a long period of voice change, and there is no obvious change in the process of voice change, but when they scream or yell like children, they find that they can't get up high or are depressed; There are also some boys (fewer) who can hardly see any change in their voices. The way they speak in adolescence is similar to that of children before their voices change. There is a coloratura tenor whose vocal cord length is actually only a little longer than that of ordinary children, while the vocal cord length of ordinary men will increase from 6 7 cm to nearly 3 times or even longer. The longer the vocal cords are, the more different the vocal feelings and habits brought to people before the contrast changes. Because the vocal cords in the voice changing period are often in a state of congestion or physiological inflammation, the vocal cords are out of control. The glottis can't be completely locked when vocalizing, which leads to inaccurate vocalization. Because of this, students at this stage are often psychologically burdened, unwilling to speak, embarrassed and shy when speaking, and afraid of classmates' jokes. , even produce tension, fear and emotional instability. The adverse effects caused by this kind of bad psychological factors, if not promptly diverted and corrected, will easily lead to vocal cord lesions in the voice change period, seriously affect students' physical and mental health and growth, and sometimes even lead to lifelong regret. Knowing this knowledge, I will try my best to take care of them (these groups) in future music classes. Students should try to avoid high notes when singing, and avoid sounding and singing for a long time. In the aspect of song selection, we should teach to sing songs with narrow range and high pitch, which is suitable for students' voice change period. At the same time, let the children's parents patiently explain the physiological characteristics of the voice change period, and educate the children not to use the voice loudly and excessively, so as not to aggravate the congestion of the vocal cords due to excessive fatigue, and then affect the normal development of the vocal cords during the voice change period. In addition, in daily life, students should also pay attention to the choice and collocation of diet, eat more fruits and vegetables, and eat less greasy and spicy food. While studying hard, they should pay attention to the reasonable arrangement of rest time and ensure adequate and regular sleep time. Good luck! I wish my child health and happiness! ! I wish your family happiness! ! !
