Which concept is primarily concerned with how high or low a sound is perceived?

• A. Frequency
• B. Noise
• C. Amplitude
• D. Waveform

Answer: (A)

Pitch is determined primarily by frequency: the higher the frequency, the higher the perceived pitch, and the lower the frequency, the lower the perceived pitch. Frequency is how fast the sound wave vibrates, measured in cycles per second (hertz). For example, doubling the frequency raises the pitch by about one octave (a higher note), while halving it lowers the pitch by an octave. Loudness is governed by amplitude, not pitch, so a louder or softer sound can be the same pitch. Noise represents a broad mix of many frequencies and doesn’t have a single pitch, and waveform describes the signal’s shape (timbre) rather than the basic pitch. So the concept linked to how high or low a sound is heard is frequency.
