Hum Update November 2015

We continue to hear from people in Calgary and Edmonton who are noticing a hum.  Frequently, similar words and phrases are used to describe that they are hearing:

• the hum sounds like an engine idling in the distance
• the hum has also been described as sounding like a train locomotive idling
• there seems to be pressure in my ear (or ears) as well as there being a hum sound present
• the hum appears to be heard wherever there is an electrical grid, even in remote areas
• the hum is louder at night than in the daytime
• when the hum is heard inside, it seldom can be heard outside
• the hum seems to have started when smart meters were activated
• the hum is a "low" sound (often around 40 hertz)
• some people can hear the hum while others cannot
• there are some people who can feel a vibration associated with the hum as well as hearing it, while some others notice a vibration while not hearing a hum-
• sometimes there is a "thrumming" sound accompanying the hum, and/or the hum sometimes sounds like it is "wavering"

We've determined that the hum is a real phenomenon and is one that can be recorded.  The working hypothesis is that the hum is man-made, or "mechanical" in nature.  As far as we know, low frequency hums around 40 hertz do not naturally occur in nature.

The challenge has been determining the source, or sources, of the hum.  That has been the puzzle that has been difficult to crack.  We welcome continuing to hear from people who have leads and ideas in this regard.  We request that these are based in scientific possibility and are grounded with facts in some way.

Thank you to all that have been in touch with us.  Please continue to do so.
