Multiple Choice

Frequency is related to which perceptual attribute?

Frequency refers to how fast sound waves vibrate, and our hearing translates that rate into pitch—the perceived highness or lowness of a tone. A higher frequency yields a higher pitch, while a lower frequency yields a lower pitch. Loudness, on the other hand, depends on the sound’s amplitude (how strong the vibration is), not its frequency. Timbre is about the quality or color of a sound, determined by the harmonic content and envelope, which lets you distinguish, for example, a violin from a flute even if they play the same pitch. Duration is simply how long the sound lasts. So, the perceptual attribute tied to frequency is pitch.
