Answer 2

Answer:

Vibration is defined as rapid oscillation of the body. The characteristics of sound are:

• Loudness - Loudness defines how loud a sound is. It is measured in a unit called Decibel (dB). It is it directly proportional to the amplitude of vibration.

• Pitch - Pitch depends upon the frequency of vibration. The more the frequency, the higher will be the pitch.

• Quality or Timbre - It determines the quality of sound.
