The property of a sound wave that determines its pitch is frequency.

Understanding Sound Wave Properties

Sound waves have several characteristics, but only one is directly related to how high or low a sound seems to us:

  • Amplitude: This affects the loudness of the sound, not the pitch.
  • Distance from sound to source: This influences how loud the sound is when it reaches us, but it does not change the pitch.
  • Frequency: This is the key factor for pitch. Higher frequencies result in higher pitches, while lower frequencies produce lower pitches.
  • Speed: The speed of sound can change based on the medium (like air or water), but it does not affect the pitch itself.

In summary, when considering pitch, focus on frequency as the determining factor.
