A strange mystery humming noise coming from the sky has spooked a small town in Canada.

For decades thousands of people across the world, including the UK, have been plagued by a drone-sounding noise known as 'the hum'.

Now one woman claims she has captured the eerie noises on film.

Kimberly Wookey of Terrace, British Columbia was woken up by a deep, rumbling sound that could be heard across the whole town.

She said that she had heard the sound before, but this was the only time she had been able to record it.

In an interview, Kimberley said: "First time was back in June - but it was not quite as intense."

When she heard the noise again she rushed to record it.

"I shot out of bed like a bat out of hell," she said.

The droning sound echoed off the mountains that surround Terrace for several minutes - prompting the whole town to ponder over the strange sound.

Mandi Campbell said: "It seemed to be coming from the sky or underground, something so loud though."

Wild speculations for what caused the noise have been flying around the web, but one city spokesperson has a simpler explanation.

Alisa Thompson claims it was a city worker grinding down a blade on a grader.

"The grader blade needed to be straightened. Kind of gets ground down, and it makes a very strange noise. It's as simple as that," said Thompson.

This is not the first time "The Hum" has been heard - Durham was plagued by a similar noise in 2011, and it has been heard across the world for the last 40 years.

Scientists are consistently baffled as to why only two percent of the population can hear this low-level hum.

Geoff Leventhall, a noise and vibration consultant who has advised the government on the issue, says that we will not know the cause for many years: "It's been a mystery for 40 years so it may well remain one for a lot longer."
