There's been a lot of buzz over the last few weeks about strange sounds being heard in the atmosphere. People around the world and here at home have reported hearing some bizarre noises. The latest were recorded in the Battlefords last weekend.

Ian Hamilton, North Battleford's mayor, says he can't explain it. "What I experienced was a scraping sound, like a snowplow."

Mike Halstead, a North Battleford resident, was lying in bed when his phone rang. Calls and text messages came in from his friends, each reporting strange noises. "That's when the goose bumps got me and I thought ‘that's awfully strange'."

It's now days after and the city is still abuzz with talk about the sounds. Everyone has his or her own theory. But the phenomenon has stretched beyond North Battleford. Similar experiences were reported in Saskatoon, northern Saskatchewan, and parts of the USA and Europe.

University of Saskatchewan professor Jean-Pierre St. Maurice says there is a natural explanation. "Somehow they are picking up noise from an electrical antenna that is there. That is electromagnetic noise. "

St. Maurice says its normal and there is nothing to worry about. Whether a scientific explanation will satisfy all the people who heard something they can't explain is up in the air.
