What is the formula to find relative sound intensity when given the angle from the source, frequency, watts and the distance?

Question

anonymous · Answer

If source emits sound with spherical symmetry ,then
Intensity is proportional to 1) Power of source
                                       2) Square of distance from source

$\huge {I \propto \frac{P}{r^{2}}}$

So, ratio of intensities at 2 points is equal to inverse square ratio of the distances of the 2 points from the source.I do not understand the role of angle and frequency. I am not confident about my answer.
