If a sound has a high frequency, it is generally perceived as having a higher what?

• A. Pitch
• B. Loudness
• C. Duration
• D. Bandwidth

Answer: (A)

The main idea is how frequency relates to how we hear a tone. When a sound has a higher frequency, the air particles vibrate more times per second, and our ears interpret that faster vibration as a higher pitch. Pitch is the perceptual attribute tied to frequency, so increasing frequency raises the tone you perceive. Other aspects—loudness depends on amplitude (how strong the vibration is), duration is how long the sound lasts, and bandwidth is the range of frequencies present—do not describe how high the pitch feels. So a high-frequency sound is heard as having a higher pitch.
