I don't understand why this is such a big problem.
1) Locate someone suffering from the hum.
2) Take expensive pressure and sound equipment to their location.
3) Record all observable frequencies.
4) a) If nothing shows up, it's a personal biological problem. Direct problem toward medical professionals b) If something shows up on the frequency graph, identify the direction the sound is coming from (again using equipment that, you know, has been designed for this kind of thing and has been around for ages).
5) Follow sound, locate source.
6) Voilà, problem solved.
Someone tell me why it's not that simple.
