Low-level HUM Bothering Anyone Else? The Windsor Hum

[compn]

To save the trouble of reading 19 pages right now, was there any conclusion to what the hum is? I was under the impression that it's airplane testing or something like that. Only hear it at night sometimes

only theories.

1. blast furnace or other equip on zug island
2. naturally occuring winds causing vibrations from bridges, buildings or land.
3. collective hallucinations [[as the hum is difficult to record, due to the low frequency)
4. trucks idling for the bridge crossing

or something else.
