The two minute and 21 second video was reshared by another YouTube channel today.
It is the latest in a string of unusual noises to heard from the sky worldwide – with unusual hums and horrific “trumpet” noises.
Scientists have been theorising what is causing this noise, with theories ranging from shifting ice to distant storms.
Krupinski shared the video of him standing in a snowy landscape, which is silent apart from a constant low buzz – and a passing snowmobile.
“Something strange is going on”
Footage begins with him filming the evening sky as the odd sound radiates across the landscape.
It is briefly interrupted when a snowmobile passes, but once it has gone the pulsing hum remains.
He was standing in any almost empty snow-covered landscape, with no obvious source of the ambient noise.
He added: “I have never heard it before. It is usually a very quiet place here. I am sure the sound came from the sky or atmosphere.
Others have speculated they could be sounds from experimental aircraft, or unannounced military drills.
Other sources of the noises have been claimed to be “space quakes” – which shake the Earth’s magnetic field.
Geoscientist David Deming from the University of Oklahoma has previously written about a phenomenon called The Hum.
He described it as “a mysterious and untraceable sound that is heard in certain locations around the world by two to 10% of the population”.
