I heard this once back in 2011 while driving alone through the country at night. Just a weird, pulsing hum. Then it vanished just as quickly as it started. It's funny that people have been studying it for so long and still have no idea what causes it.
Some mystery hums have been tracked down to a source but it can be tricky as the sound travels quite a long way.
This is the best summary I could come up with:
The night-time noise has been reported in a wide area of the County Tyrone town in recent weeks.
Now, noise experts could be called in by the council as it struggles to find the source of the mystery hum.
He was initially contacted by people in the Tamlaght Road area of Omagh in late October, but in the weeks since reports of the mystery noise have spread to other parts of the town.
Mr Donnelly said people "usually characterise it as a persistent buzz or hum" that was distinct from more common noise such as traffic.
"It may well be that it's seasonal or weather-related but these things often don't turn out to be simple and it may be a multitude of sources," said Mr Donnelly.
A phenomenon known widely as "the Hum" has been reported across the globe over the past five decades, including in the UK, North America and Australia.

As this community is on Feddit.uk it takes a British approach to things but it needn't be restricted to the UK - if it's weird and unusual it probably has a home here.
