Cracking the mystery of the ‘Worldwide Hum’

  In the spring of 2012, when I was living near the coastal village of Sechelt, on British Columbia’s picturesque Sunshine Coast, I began hearing a humming sound, which I thought were float planes.

  The noise usually started later at night, between 10 and 11 p.m. My first clue that something unusual was happening came with the realization that the sound didn’t fade away like plane noises typically do. And the slightest ambient noise – exhaling audibly, even turning my head quickly – caused it to momentarily stop. One night after the sound started, I stepped outside the house. Nothing.
