Question
Shows the wave patterns of three sounds A, B and C. Name the characteristic of sound which is same between
- A and B,
- B and C, and
- C and A.
| A | B | C |
 |
 |
 |
Solution
- Since both have the same amplitude and waveform, the loudness and quality are the same.
- Neither amplitude nor waveform are the same. Hence, no characteristic is the same.
- In this case, the frequency of both sounds is the same, so their pitches are the same.
