When air is pushed past the vocal folds with sufficient pressure, the vocal folds vibrate. If the vocal folds in the larynx did not vibrate normally, speech could only be produced as a whisper. Your voice is as unique as your fingerprint. It helps define your personality, mood, and health. Approximately 17.9 million adults in the United States have trouble using their voices. Disorders of the voice involve problems with pitch, loudness, and quality. Pitch is the highness or lowness of a sound based on the frequency of the sound waves.
When you shout with too much force, it is possible to damage the lining of your vocal cords, causing hoarseness. The muscles in your throat tighten, and breathing becomes shallower in reaction to the excessive tension. This results in more effort being exerted to recover your voice, which can make it worse. If the voice isnât given time to recover from stressâif you shout while your voice is still hoarse and your throat is still soreâyou risk damaging the vocal cords still further.
