äänihuulia

Äänihuulet, also known as vocal cords, are two bands of muscle and connective tissue located within the larynx, or voice box, in the throat. When a person speaks, sings, or makes any vocal sound, air from the lungs is expelled upwards through the trachea and into the larynx. This airflow causes the äänihuulet to vibrate. The frequency of these vibrations determines the pitch of the sound produced; faster vibrations result in higher pitches, and slower vibrations produce lower pitches.

The tension and length of the äänihuulet can be adjusted by muscles within the larynx, allowing for a wide range of vocalizations. When the äänihuulet are brought close together, they can vibrate to produce sound. When they are pulled apart, air can pass through unobstructed, allowing for silent breathing. The specific characteristics of an individual's äänihuulet, including their thickness, length, and elasticity, contribute to the unique quality and timbre of their voice. Conditions affecting the äänihuulet, such as inflammation, nodules, or paralysis, can lead to voice disorders like hoarseness or a complete loss of voice.
