What is the mean pitch for adult females in Hz according to typical norms?

The mean pitch for adult females typically falls within the range of 225 Hz. This value represents the average fundamental frequency heard in speech and is influenced by various anatomical and physiological factors specific to adult females, such as the size and tension of the vocal folds. Understanding this average is crucial in fields like speech science, voice therapy, and vocal training as it helps to set normative standards for assessing voice characteristics in clinical and educational settings.

The other options, while they may represent pitches in other contexts or populations (such as children or different vocal classifications), do not align with the established norm for adult females.
