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.

REMINDER Mysterious Ranchlands Hum Public Presentation

Press Release - Sep 20, 2011

----- PRESS RELEASE -----

Recent findings regarding the investigation into Calgary's Mysterious Ranchlands Hum will be presented Wednesday, September 28, 7:00 PM, at the Ranchlands Community Centre.

The Ranchlands Noise Investigation Team, a group of volunteers coordinated by Dana Negrey, have been donating significant time, equipment and money to determine the cause of the humming noise plaguing numerous Ranchlands residents. Since beginning the investigation in 2008, the team's Acoustical Engineer Richard Patching has recorded the Hum, having presented the evidence at the 2010 Ranchland's AGM.

The team, including Dr. Marcia Epstein, Dr. Kathleen Biersdoff, Dr. Mike Smith & Terry Avramenko and many other volunteers, has made additional findings. Most significant of these was a result of a June 8, 2011 test coordinated through the cooperation of The City of Calgary's Chris Huston & Alderman Gord Lowe. The Bearspaw Dam's main pump, a suspected source of the noise, has been ruled out as a source of the Hum.

The team continues to investigate other possibilities as to the cause of the Hum. Dana Negrey will present these at the September 28th AGM.

Increasingly, the team is receiving more and more reports from around the City of Calgary, and further abroad, suggesting this phenomenon extends beyond Ranchlands. The team believes that if the problem can be solved in the Ranchlands community, then the far-reaching benefits to other communities could be significant.

The team gratefully acknowledges the support of the Ranchlands Community Association, Alderman Gord Lowe, Chris Huston & his team, the many volunteers that have assisted in this investigation and members of the media following our story.

Water Services, Twitter and Facebook - the Mysterious Hum Investigation Continues

The team investigating the Ranchlands hum met in April. Plans to coordinate a test with the City of Calgary Water Services were put into the final phase. The test will entail shutting down some of the water pumps that are part of Ranchlands water system. Residents who have been hearing the hum will be asked if they noticed any differences between when the pumps were on and off.

At the time of this article's writing, the City and team were still trying to coordinate when this test will take place. It appears likely that the test will take place in June, during a weekday evening. The date and time the test will occur will be shared with Ranchlands residents.

The team continues to hear from residents who are noticing the hum. People have reported hearing a low sound throughout their homes. In some cases, this hum has only recently noticed. The team encourages residents who are hearing the hum, or other 'odd' noise in their homes, to please be in touch through the Ranchlands Community Association at 403-241-0321.

The team has taken advantage of social media. They have a Facebook page set up titled "Ranchlands Hum" and a Twitter account @jmidi. Residents are welcome to follow the team at these locations. The blog can still be found at

The team would like to thank the Associaiton and community for their patience. This type of investigation takes a fair bit of time. Your continued support is greatly appreciated.

Noise Investigation Team To Meet

The Team investigating the Mysterious Ranchlands Hum will be meeting soon to determine the next steps in our hunt for the source of this disturbing sound. We will let the public know afterwards.

Sunday, January 9, 2011


The Ranchlands Hum still plagues a number of residents. Happily, the City of Calgary is willing to help seek a resolution to the problem. The Noise Investigation Team, in conjunction with the City, wants to intensify the search efforts.

The first step in this direction is for the team to work with Calgary Water Works. The team has learned there is an auxiliary pumping station near Ranchlands that may or may not be a contributing factor to the Noise.

Water Works has said they are willing to arrange at test whereby they would shut the pumps down and see if the Noise goes away. In order for this to work, people affected by the Noise would have to be home and listening, shut things off and on in their individual homes and report any changes.

The team would like to hear from any Ranchlands residents interested in participating with this phase of the investigation. Once the team determines how many participants they are, arrangements will be made with Calgary Water Works. The time and date of the test will be made available soon afterwards.

Please contact the team either through the Ranchlands Community Association at 403-241-0356 or via email at
