    The relationship of the two is that, the sound intensity is inversely proportional to the square of the distance of the source.

    I α 1 / r^2

    Where I = intensity and r = distance from source

    From this, we can equate two conditions 1 and 2:

    I1 / I2 = r2^2 / r1^2

    So when r2 = 2 r1, the intensity becomes:

    I1 / I2 = (2r1 / r1) ^2

    I1 / I2 = 4

    I2 = I1 / 4

    So when we double the distance of the source, the intensity of the sound reduces by a factor of 4 (divided by 4).
