After the BBC4 interview in Winnipeg, I went off the grid on a small and fairly isolated island in the region of Kenora, Ontario, in the Lake of the Woods, a massive lake that spans the Canada-United States border. I’m back home now.
The Hum was very loud – much louder than in my home town in BC, Canada. In fact I could often hear it well during the day, even with a wind blowing. The night before I left the island, I awoke at around 3:00 a.m. and for the first time in several years, the Hum was a distraction, bordering on an irritant. So I took out my phone, put in my earbuds, and launched the tone generator app. Yet again, as usual for me, I perceived a dominant tone that centred at around 56.5 Hertz.
I was thousands of kilometres away from my home town. Why was the tone the same? How could an acoustic source explain this? I speculated on this until just before I finally drifted back to sleep, I heard the sound of a train whistle. The nearest tracks were almost 15 km away.
Among the many emails I just sorted through, a few were from people with serious scientific credentials, and I am excited to engage with them over the next few weeks while I get ready to test the Deming Box again.
