A resident of British Columbia (province of Canada) Glen MacPherson created a website dedicated to the unexplained phenomenon known as the "hum of the Earth."
MacPherson himself first heard this strange sound in 2012. At first he assumed that the low hum was coming from seaplanes, but later found out that this was not the case.
The puzzled MacPherson began to search for suitable information on the network and found out that many people in different parts of the Earth hear a similar hum, and that this phenomenon even has a name.
Many suspect the hum is caused by low-frequency radio waves used by the military to communicate with submarines.
Other people are convinced that hum is a collection of a range of sounds associated with human activities, from cars and traffic to various forms of industry.
According to the third popular version, hum is a consequence of natural geological processes.
During his online research, McPherson discovered a community interested in hum. There he found many other insane versions, and the very crumbs of scientific data or evidence. To somehow fill this gap, McPherson (a schoolteacher by profession) created a website called The Rumble of the Earth: Map and Database.

McPherson collected testimonies from people around the world and registered each of them in his database. To date, there are more than 9,000 such testimonials. However, MacPherson admits that there is still some bias in the data, since the site is available mainly to English-speaking users.
In addition, MacPherson is experimenting with a special steel box, inside which a space is formed, free from low-frequency radio waves. If the strange rumble is heard only outside the box, but not inside, it will mean that the sound is produced by radio waves.
McPherson has already built a steel box and plans to begin his experiments on the Sunshine Coast soon.
If the experiments go well, McPherson intends to move his box to other provinces and countries to explore the "hum of the Earth" outside of British Columbia.
