Let have 3 microphones MIC1: @ mic1x,mic1y MIC2: @ mic2x,mic2y MIC3: @ mic3x,mic3y. MIC1-MIC2 separated 2500mm at 90degr MIC2-MIC3 separated 2500mm at 90degr

If a sound produced by source S reach MIC1 with a peak of let's say 75, MIC2 of 20 and MIC3 of 10. How could I locate the audio source?

    I might be wrong, but I think this might belong to physics.stackexchange. Basically, you need to check the rate of volume dissipation (should be something quadratic, I think...), and then use that to calculate the distance to each of the three points, and that to find the location. Well, assuming it's an empty room, that is...2012-09-02

    A microphone in fornt of me will "hear" more of what I say than one in the same distance behind me (well, that may here other sounds better). I assume that timing differences might be more accurate.2012-09-02

    Also, the microphones themselves may not hear equally well in all directions. They can be designed explicitly to approximate this, but if you just pick some random mics off the shelf in the electronics store for your location system, you can't be sure either way.2012-09-02
