Question
A change in amplitude of a sound wave is noticed.
- Which characteristic of sound is affected due to the above change?
- How is amplitude related to your answer to part (a) above?
- What happens to the quality of the sound?
Solution
- Loudness
- Loudness is proportional to the square of its amplitude i.e., `"L" prop ("a")^2`
- The quality of the sound does not change because quality is dependent on the waveform.
