Decreases by times
Explanation:
The intensity of a sound is defined as the energy of the sound that is flowing in an unit time through the unit area which is in the direction that is perpendicular to the direction of the sound waves movement.
The intensity of energy is described by the inverse square law. It states that the intensity varies inversely with the distance square of the distance.
In other words, the sound intensity decreases as inversely proportional to the squared of the distance. i.e.
In the context when the distance was 3 m, the intensity of the sound was =
But when the distance became 6 cm or 0.06 m, the sound intensity decreases by =
= times
