Ranchlands hum mystery still stumps researchers

Volunteers researching a mysterious hum in northwest Calgary say the outcome of a similar study in Ontario gives them hope.

Richard Patching and others have spent at least five years trying to pinpoint the source of a bothersome noise in the neighbourhood ofRanchlands.

• Ranchlands hum eludes residents two years on
• Mysterious Windsor Hum traced to Zug Island, Mich.
• Windsor's mysterious hum is real, says researcher

Nowthey say they are narrowing down the mystery but are getting stalled by a lack of resources.

"If we can convince the people who have the sources of funding that this is a problem that is needful of attention and I think with the Windsor one, it brings it to the attention of the people who have that power that's a hopeful sign," said sound engineerPatching.

A $60,000 federal grant recentlyhelped a dedicated team of researchers pinpoint the source of a similar hum in Windsor, Ont.

Patchingsays that kind of money could help them, and they may try to raise it through crowdfunding.

For residents in the area, the noise has been a source of irritationsince reports of the sound first surfaced in 2008.

"Something like a very large truck or airport engine idling at a distance," says Marcia Epstein, an acoustic ecologist who lives in the area.

Epstein says they have managed to narrow the cause of the noise down, mainly by eliminating ideas about what it could be.

She says they have concluded it'snot related to any of the construction sites or electrical systems in the area.

However, they have notruled out that it could be related to the water system and are hoping that some money and high-tech equipment willlet them finally solve themystery.

The source of the mysterious hum in Windsor was determined to be Zug Island, a steel manufacturing site in Michigan across the Detroit River from the Ontario city.
