Which description best captures the term "pitch" in relation to frequency?

The term "pitch" specifically refers to the auditory sensation that corresponds to the frequency of a sound wave. In acoustic terms, frequency is the number of cycles a sound wave completes in one second, measured in Hertz (Hz). A higher frequency results in a higher perceived pitch, while a lower frequency corresponds to a lower perceived pitch. This relationship is fundamental in fields such as music and speech, where pitch variation plays a key role in melody and intonation.

Understanding pitch in this way underscores its dependence on frequency, making it clear why option B is the most accurate description. It captures the essence of how we perceive sounds in terms of their frequency-based characteristics, which are crucial for distinguishing different tones in speech and musical contexts.
