A Mysterious Sound Is Driving People Insane ?" And Nobody Knows What's Causing It
• http://mic.com/articles/91091/a-mysterious-sound-iDr. Glen MacPherson doesn't remember the first time he heard the sound. It may have started at the beginning of 2012, a dull, steady droning like that of a diesel engine idling down the street from his house in the Sunshine Coast of British Columbia
Sorry, but if you can drive 10 miles in one direction without it attenuating or growing stronger, and then at a 90 degree angle do the same then the hum is in your head. Which explains why nobody else is hearing it.
Thank dog the sound is that of a car idling and not a trumpet.
