What is the term for the frequency of sound perceived as high or low?

• A. Fluency
• B. Pitch
• C. Articulation
• D. Intonation

Answer: (B)

The term for the frequency of sound that is perceived as high or low is pitch. Pitch is a fundamental aspect of sound that relates to the frequency of vibrations producing that sound—higher frequencies result in sounds being perceived as higher in pitch, while lower frequencies correspond to lower pitches. This concept is crucial in the study of speech and music, as it influences tone, melody, and overall auditory perception.

Fluency, on the other hand, refers to the smoothness or flow of speech, which does not pertain to the frequency of sound. Articulation involves the clarity and distinctness of speech sounds but also does not relate to pitch. Intonation is the variation in pitch while speaking, but it specifically refers to how pitch changes over the course of a spoken utterance rather than the concept of pitch itself. Thus, the correct answer highlights the specific auditory sensation of frequency, which is captured accurately by the term pitch.
