Question

Quizplus · Accepted Answer

The force with which air rushes across the vocal folds determines the loudness of a person's voice. When air is forced through the vocal folds, they vibrate more vigorously, producing a louder sound.

Answer choices A, C, and D are related to different aspects of voice production, but not specifically to the loudness of a person's voice. The length of the vocal folds affects the pitch of the voice, while the thickness of the vestibular folds and strength of the intrinsic laryngeal muscles affect the quality of the voice.
