g To decrease the intensity of the sound you are hearing from your speaker system by a factor of 36, you can

Increase the distance by a factor of 6.

Explanation:

The intensity at a distance r is given by :

Here,

P is power emitted

r is distance from source

It means that the intensity is inversely proportional to the distance from the source.

To decrease the intensity of the sound you are hearing from your speaker system by a factor of 36, we can increase the distance by a factor of 6. Hence, this is the required solution.
