Vocal folds (cords) are two flap-like structures that vibrate to produce sound, with different pitches corresponding to different oscillation frequencies (e.g., A4 at 440 Hz). The Bernoulli effect causes vocal folds to close when air pressure is applied, creating the sound. Proper vocal closure is essential for voice longevity because air leakage through partially closed folds dries out the mucosal lining and causes friction. Voice changes naturally over time due to aging, pregnancy, and overuse, and individuals should understand their unique vocal characteristics to preserve their voice.
