The picture below shows three sound waveforms. They differ in ____.
- Pitch
- Loudness
- Quality
- All of the above
Hint:
Loudness depends on amplitude.
The correct answer is: Loudness
- The loudness of a sound depends on the amplitude of the wave.
- In all three waveforms, the amplitude is different for each.
- Therefore, they differ in loudness.
