Question

How can sound intensity be controlled?

Answer 1

Varying the vibration from the beginning of the oscillation.

Explanation:

The intensity of sound is basically the loudness of sound.

So in general terms, you would need to reduce the volume, but looking at this concept in terms of wave motion, one must vary the intensity of the vibration in the longitudinal plane.

If the vibrations are mild, the sound wave will be less intense.
