Request to hear from people noticing Hum or Noise

If you, or anyone else you know, is hearing an unidentified Hum or Noise, we want to hear from you.

We have expanded the scope of our search from Calgary and are now collecting data from Edmonton.  We are interested in continuing to hear from people in those two cities, plus any other areas, particularly in Alberta.

Thank you.

Edmonton Observations

There may be a Hum issue in Edmonton, too. Not much has happened with the Hum investigation in Ranchlands, unfortunately. However, with one of our team members recent observations in Edmonton, we would be interested in hearing from others who have similar stories to share. Is this an urban phenomenon? What's causing it? We would surely like to find out the answer to this perplexing puzzle!

May & June, 2012

Residents in Ranchlands, continuing to live with the ongoing Hum, have noticed a bit of a pattern lately. There have been days when the Hum has been absent in the morning. On those days, the Hum starts up with a fair bit of regularity after 4 PM. An interesting observation. We would like to hear comments from others who may or may not be noticing similar patterns in their own homes.

Easter, 2012 & The Hum Is Increasing In Popularity

The Hum has gotten quite prevalent these last few weeks in our house. It seems that it is being heard in more houses in Calgary, too. The Team is receiving reports from residents in other NW sectors of the City being bothered by the Hum, and by more Ranchlands residents. If you are now noticing it for the first time, or perhaps more frequently than you did before, please let us know.

Post-Meeting Update from the Noise Investigation Team

Dana Negrey provided the community a summary of the work done by the Noise Investigation Team seeking the Ranchlands Hum:

1. Water system: The test coordinated with the City of Calgary Water Services has ruled out the Bearspaw Dam pumping station as a source of the Hum. There are intermediary pumping stations between Ranchlands and the Dam that the team will next be looking at. The Team is continuing to operate on the working hypothesis that the Hum is being carried into various residents' homes via the water pipes. However, the source of the Hum continues to be elusive.

2. EMF/cell towers: The team will explore the potential of EMF energy and/or cell towers being the source of the Hum. This avenue of investigation will be explored, if need be, after a more in-depth look at the water system.

3. Gas Lines: the team has learned of an occasion when a Ranchlands resident noticed changes in the Hum corresponding to work done on the gas line into her house. Specifically, she noticed that when pressure in the natural gas line was eliminated (i.e. the gas in the line to her house was turned off) the Hum disappeared. When the line was back under pressure, she reported the Hum started up once again. The team would like to hear from other people who have had similar experiences, whether in Ranchlands or elsewhere.

4. Thank you: the team recognized the efforts done by City of Calgary Alderman Gord Lowe and City of Calgary Water Service's Chris Huston for assisting with the Bearspaw Dam test in June, 2011. The team is grateful, too, for the continued support of the Ranchlands Community Assocation.
