Frequency and Pitch
- The frequency of a sound wave is related to its pitch.
- Sound waves with higher frequencies (treble) are described as having a higher pitch.
- Sound waves with lower frequencies (bass) are described as having a lower pitch.
- Pitch, however, is not objective and does not have units of measurement; it is usually used to compare different sounds and can have a perceptual bias.
Amplitude and Loudness
- The amplitude of a sound wave is related to its loudness.
- Sound waves with greater amplitudes will be louder than sound waves with smaller amplitudes.
- Similar to pitch, however, loudness is subjective and our perception of how loud a sound is depends on its frequency and the type of sound.
