What about The Hum?

It is close to November and there are different sounds outside than in summer.  Perhaps one notices these sounds in the later fall rather than the summer.  There is a lot more wind, so noises get to us that might not have travelled as far.  And the wind itself is quite noisy.

Can it be that the electric hum around transformers and on power lines only happens in the late fall?  I have looked this up and the humming sounds are caused by stray magnetic fields causing the enclosure and accessories to vibrate. Power lines make noises when it is hotter out, rather than colder.  Power lines can emit a buzzing sound when it is raining or wet outside, the air is "ionizing".

This is different than "The Hum". The World Hum Map and Database Project is HERE.  This is a world mystery.  Most people find the website when they are disturbed by an unusual unidentified low-frequency sound that scientists now call the Worldwide Hum.  At this site, you can see the entries in the World Hum Map and Database and there are 10,000 plus map and data points..  Here is an excerpt from the overview:

"The classic description is that The Hum sounds like a car or truck engine idling outside your home or down the block. Some people describe it as a low rumbling or droning sound. It is typically perceived louder at night than during the day, and louder indoors than outdoors. The sound can usually be masked by background noise, such as a fan or keeping the radio on. We estimate that 2-4% of the global population can experience this phenomenon under certain conditions".

The first records of the Hum were in England in the late 1960s. There are investigations to find out if there are occurrences going back to the 18th and 19th centuries.  This is a great scientific mystery that is receiving increased scientific attention - you can check out the Wikipedia entry HERE.   In the U.S., the Taos Hum has been documented extensively. In fact, there's a YouTube recording of 12 hours of The Hum.

Today's picture is the back garden at Nelles Manor, the oldest house between Kingston and Niagara-on-the-Lake.  this actually was the front of the house.  Main Street was re-routed so it became the back. The Nelles property stretched from the escarpment to Lake Ontario, so it seems interesting that the road was in the front to start.
