typical triangulation would depend on the sound being heterogeneous in waveform/volume right? If it's a constant hum then you'd only have volume dissipate as you move away which would get a lot harder as sound has different loss functions as it moves through different materials.
- LeifCarrotson 9y agoNo, the triangulation you would use for a project like this would look for time delay or phase lag between 2 (or more) adjacent microphones. The sound pressure wave is picked up by one, then some few microseconds later, it appears on the other(s) a few centimeters away. This is pretty straightforward with ordinary sounds that dominate the signal. You could pick out the wire which was struck in a piano, and even the nodes and harmonics along its length. It gets more difficult at lower frequencies and with quieter signals, which precisely describes this exact situation.
