One line of inquiry that I have been thinking about recently is the perceived frequency of the Hum I hear in the region of the Lower Mainland of Vancouver, BC, Canada. The Hum Database asks for this information, but unfortunately, very few people have used a tone generator (which are free and all over the internet) to match what they seem to be hearing. If we had better information here, we might be able to start sorting out the issue of whether there are multiple hums.
I think it’s too easy to jump right to the conclusion that “there are many hums”. For example, there is a minority (but very vocal) school of thought that high pressure gas pipelines are responsible for the Hum. As always, I ask the most basic questions regarding the locations and timing of the first reports of the Hum, followed by questions about how pipelines cause the Hum hundreds of kilometres away, where there are no pipelines or any significant industrial activity. How can the Hum suddenly stop, or appear, for days or weeks or months if pipelines are responsible? These troubling questions are set aside with a wave of the hand and the response “there are many hums”, and so one need not dwell on the apparent logical problems with any one theory.
Muddying the waters further, Novak, who investigated the Windsor disturbance, described the sound himself as an idling diesel engine, which is the classic description of the Hum. Almost nobody picked up on this comment, which I think conflated Windsor with the rest of the world and was a real setback to those of us interested in researching the worldwide Hum. Zug Island may indeed be causing all sorts of sonic trouble around Windsor, but my guess is that the worldwide Hum affects that region as well, but because of the existing audio spectrum, it cannot be detected.
Science does not choose winners based on who is the most charismatic, best organized, loudest, or the most prolific with commentary. At a certain point, the brainstorming and arguing must stop and the controlled experiments must begin. If those experiments yield results, they must be replicated. Only then should we speak with confidence about what is causing all this.
And this generalizes to other theories, from cell phone towers to the electric grid to HAARP, Broadband over Power lines (BPL), and so on. People get emotionally attached to their theories, and some folks likely have a fear that all the time and emotional energy they’ve invested in trying to convince others about the source of the Hum will have end up being wasted. And I think from a psychological point of view, it can be attractive to free ourselves from troubling facts.
Show me the science.
