The direction of the distribution doesn't matter. If the microphone is not connected to the speaker, then the microphone senses 30 dB at a distance of 0 m from the speaker with the decibel level decreasing by 8 for every additional meter from the speaker. In the equation above, \(c\) is a constant. When you multiply or divide both sides by a normal number, they get larger or smaller by a set amount, and the side that was greater before is still greater now.
