In March of 1994 I experienced something like the Taos Hum but it was an inaudible vibration. Lived in SE Michigan at the time, and years later found a cluster of Western Lake Erie hum reports. I only called it the Taos Hum because that is all I had ever heard of when internet research became available. If I described how it happened and then persisted, I’d be laughed off the page, even here.
Not by me! I want to hear you story!
Here you go.
‘The Hum’: The Unexplained Noise 2% of People Can Hear

The hum has been heard by millions of people, so no laughed off page. There is never a specific spot or direction, but you must be in a quiet environment to hear it - no road noise or other ambient sounds - indoor or outdoor, makes no difference.
Its possible it is some sort of piezoelectric phenomenon - quartz stone under pressure gives off clouds of ions which are electrically charged and there might be some sort of sound associated with this which we hear as a hum (just speculation the last bit).
