Answer the following questions:
What does the intensity of sound depend upon?

Answer

The intensity of sound depends upon:
Amplitude of vibrations: The intensity of sound is proportional to the square of the amplitude of vibration.
Frequency of vibrations: If frequency is higher then intensity of sound is also higher.
Distance from the source of sound: If the distance between the listener and the source of sound is less, then intensity of sound can be felt greater.
