उत्तर
- Loudness:
- It is defined as the characteristic of a sound that enables us to distinguish a weak or feeble sound from a loud sound.
- The loudness of a sound depends on its amplitude.
- Higher the amplitude louder will be the sound and vice-versa.
- When a drum is softly beaten, a weak sound is produced. However, when it is beaten strongly, a loud sound is produced.
- The unit of the loudness of sound is the decibel (dB).
- Pitch:
- The pitch is the characteristic of sound that enables us to distinguish between a flat sound and a shrill sound.
- The higher the frequency of sound, the higher will be the pitch. High pitch adds shrillness to a sound.
- The sound produced by a whistle, a bell, a flute, and a violin is high pitch sounds.
- Quality or Timbre:
- The quality or timbre is the characteristic of sound that enables us to distinguish between two sounds that have the same pitch and amplitude.
- For example in an orchestra, the sounds produced by some musical instruments may have the same pitch and loudness.
