abnormal sound
Introduction
Introduction When a normal person speaks, the voice is clear and round, full and rich. If the voice of the voice shows dumb, sputum, sand, and hair, it is often a sign of throat disease and other diseases of the body. Abnormal sounds mainly refer to the abnormalities of people's various voices such as voice, crying, humming and nasal polyphony.
Cause
Cause
Improper vocalization or excessive vocalization can also be caused by a strong vocalization, so this disease is more common in patients with occupational or excessive use of voice, but also secondary to upper respiratory tract infection. Various causes of chronic laryngitis can be caused by a variety of throat, vocal cord diseases, in addition, hoarseness can also be seen in excessive use of ultrasound, acute pharyngitis, vascular neurolargic edema, laryngeal tuberculosis, thyroid adenocarcinoma, rickets, systemic weakness And surgery or trauma caused by paralysis of the recurrent laryngeal nerves or injuries.

First, the voice is abnormal
If the voice is high, there are more words, most of them are real fever, the disease is in the heart and the liver; if the voice is weak, the voice is low, the sound is not hard to listen to, the silence is silent, the reaction is slow or slow, most of them are debilitating syndrome. The disease is in the lungs, spleen and kidneys; the voice is heavy and turbid, and most of them are gas-stasis and stagnation. The disease is in the liver and gallbladder.
Second, the crying sound is abnormal
The abnormal crying sound is more common in children, which is of great significance for the diagnosis of pediatric diseases. If the child suddenly cries at night, it is mostly horrified, and the mind is not guarded; if the crying voice is hoarse, it belongs to liver qi stagnation, or lung and kidney yin deficiency.
Third, the humming sound
If the patient has a snoring sound, heavy and long-lasting, it is hot; no snoring, breathing is short and short, it is spleen and lung qi deficiency.
Fourth, nasal polyphonic
The patient's nasal turbidity is heavy, the snot is thick yellow and more, it is food stagnation, the disease is in the spleen and stomach; the nasal breath is weak, the nasal sputum is thin and more, and it is weak in the spleen and stomach or insufficient in the kidney.
Five, voice variation
The child voice becomes the sound process of adults, called the voice change period. During the voice change period, some gay thyroid cartilage develops faster, the vocal cords develop slowly, the vocal cords are pulled tightly, the vocal cords are smaller in amplitude, the frequency is faster, and the pitch is higher. The voice is like a woman, called "male female tune." During the voice change period, some lesbian thyroid cartilage develops slowly, the vocal cords develop faster, or male hormones such as testosterone propionate are used. The vocal cords have larger amplitude, slower frequency, lower pitch and sound like a man. Called "female male tone."
Diagnosis
Differential diagnosis
1 When speaking, the voice is rough and low, the pronunciation is laborious, and the morning is more serious, which is common in acute inflammation of the throat. When speaking, the voice is low, rough and hard or broken, the morning is lighter, the afternoon is aggravated, and it is often necessary to quiet the throat before speaking, which is common in chronic laryngitis.
2 When speaking, the voice is hoarse, progressively aggravated, and has difficulty breathing. Finally, it can be completely aphasia, suggesting that it may be a malignant tumor of the throat. Experts have suggested that men over the age of 40 (especially smokers) suddenly appear hoarse. If they do not improve for more than a week, they should be alert to laryngeal cancer and go to the otolaryngology department for detailed examination for early diagnosis and timely treatment.
3 When speaking, the voice is hoarse. At the beginning, there is no change in the bass, but the treble is broken (hair "hair"), and the sound is easy to fatigue and cannot last. Afterwards, it gradually increased, and the sand appeared dumb. The hoarseness gradually developed gradually, and finally there was persistent hoarseness, which was common in vocal cord nodules (also known as singer summary, teacher summary, vocal granules).
When people reach old age, due to physiological changes, the pitch, sound intensity and length of the sound gradually decrease, and often tremble, forming a special "old man voice." This is not a morbid state, it is a functional vocal disorder. However, it should be noted that many elderly diseases can also cause special changes in the voice of the elderly. For example, chronic bronchitis not only affects the patient's ventilation function, but also damages the vocal cords, making the sound hoarse; when suffering from emphysema, the breathing is shallow, the "windbox effect" of the lungs decreases, the exhaled airflow speed becomes slower, and the air pressure decreases. The sound can become extraordinarily low and weak; when the heart is insufficiency, the body is in anoxic state, the respiratory system is aggravated, and the sound sounds low and urgent; the onset of cerebrovascular disease can often cause language central dysfunction or lingual paralysis, causing sound. Unclear until the sound is lost. Many experienced doctors are often able to listen to illness based on changes in the voice of older patients.
