Secret tunnel digging machine noise?

"The noise - compared to the roar of an engine and the honk of a fog horn - has been blowing in from near the Bay Ridge Channel for nearly a year, but nobody has been able to pinpoint its source. ... inspectors scoured the neighborhood, the treatment plant and the Brooklyn Army Terminal, but found no clues." - NYDailyNews
