Hello, sir!

If your observers are on the symmetry plane then, I think, you can use assumption of two coherent sound sources.

so i can multiply the fft result by 2 right

If your situation corresponds to the one with 2 coherent sources of the same power, then undoubtedly yes, you can multiply FFT by 2.
