The output of the mics is inversely related (presumably by the square of the distance in an environment with no reverberation) to the distance from the sound source but would not be of much practical use in this equation.
H1 and H2 could represent the output of either mic, depending on whether you wanted a negative value or a positive one.

Sound intensity will decrease as the square of the distance from a noise source that is small compared to the distances involved. Because of the inverse relationship, let H1 = 1/distance to closer mike, H2= 1/distance to farther mike. (1/4)/(1/18) =18/4 = 4.5. This ratio squared is 20.5. 20log(20.5)=26 db.

Sound produced at the mid-point would represent H1.
